02 S-10 V6 vortec turns over but will not start?
In Chevy S-10
You need fuel, spark and compression. You are missing one of those, probably fuel (bad fuel pump).

Why a Car Would Turn Over But Not Start Lay answer: in addition to the battery voltage to "turn the engine over"...ignition requires spark and gas. I'm having the same problem with our 86 Volvo. The mechanic says the spark plugs are providing the spark...but fuel isn't getting to the cyliders. It'…s probably a blown fuse to the fuel pump or a bad fuel pump...or more remotely a poor connection between the fuse and the fuse clips...or a leak in the fuel line. Our car has two fuel pumps and since our problem has been intermittant, like yours, and we've checked fuses and connections, we're betting it's one of the fuel pumps pooped out. Here are more opinions and answers from other FAQ Farmers: . If I remember right I think compression is the 3rd element to an engine running. timing belt or timing chain? You need to eliminate each one(fuel,spark or compression)first and then continue narrowing down from there. I have seen dampness cause ignition wires to fail among a multitude of others. Have a real tech troubleshoot it, other wise your gonna replace good parts guessing. . It is one of three things. It isn't getting proper spark, proper fuel, or proper compression. Use the process of deduction and find out. If the engine turns over the starter isn't bad. . Well it depends on the car but it could be that you don't have spark, you could have a big vacuum leak, timing might be off. But don't flood your motor if your in a hurry! . There are several possibilities: lack of fuel, sprk or compression, these are possible Maintenence items among many other possiblities: spark plugs (worn), ignition wire (Worn), distributor cap (worn), distributor rotor (worn), fuel filter (too dirty), air filter (no air getting in) and timing belt (timing is off). . It is worthwile to check for spark from the coil before considering the distributor, spark plug wires or sparkplugs. Assuming that lack of spark is the problem. . Another thing it could be is that your car is flooded , requiring possibly 3 hours for plugs to dry. . I had a problem on a 1994 ranger that turned out to be a motion switch that had been tripped when the car was bumped. It caused the electric fuel pump not to turn on. . If the car is a Chrysler product and just cranks but won't fire, it could be the fusible link. On Ford and GM cars the car will not even crank if it is bad but on Chryslers it will just crank. I don't know about imports. . Other possible sources of fuel related problems are a collapsed fuel line(depending on how old the car is) or plugged filter. Before you drive yourself nuts trying to locate the fuel shut off that the fellow described on the ranger.....it's been my experience that is only on ford models(you don't say anything about your make or yr)in the trunk in cars. Good luck . Correction: It's primarily fuel, spark, and timing. Timing problem of course can lead to lack of compression. Clarification: The comment on the '94 Ranger is correct. Many Fords have what is called an "inertia switch" which will cut off the fuel pump. This is designed to benefit the occupants in the case of a severe accident. I don't believe any other domestic maker uses this, but some imports do such as Jaguar. . A GASOLINE internal combustion engine needs 3 things to function properly: 1) fuel, preferrably delivered at the right mixture, but generally if it's there and the other two components are met, the engine will at least run. 2) ignition, often referred to as a spark or fire, ignition timing must be within a couple degrees of factory settings otherwise the engine may not run at all. Ignition spark strength must also be high enough to be adequate for the air/fuel mixture to ignite, but generally it is an all or nothing situation in the newer, electronic ignition systems. 3) compression, if the compression is up, the cylinders, valves and camshaft are functioning adequately and the timing chain/belt/gear is timed properly. If all three of the above conditions are met, the engine will start when it is cranked. To find out why it won't start, you have to find out which of the above conditions isn't being met. Rather than approach the problem in a "shotgun" manner, it's best to be methodical in your approach. First, spray some starting fluid into the air intake while a friend tries to start the engine. If the engine runs briefly while you are spraying starting fluid, you have good reason to believe that the engine is not getting fuel... item 1 on the requirements. If the starting fluid didn't give you any clues, pull a sparkplug wire from the plug (any one will do) and connect it to a spare sparkplug. Set the sparkplug on a solid metal part of the engine and have your friend crank the engine again while you watch the sparkplug. You should see a bright spark if the ignition is working properly. And finally, if the above two tests didn't give you any information, run a compression test. Since all valves and all cylinders don't generally fail at the same time, you'll only be testing the timing of the camshaft, but that's pretty important. Mark the location of each sparkplug wire. I generally use a piece of masking tape with the cylinder number, then wrap the tape around the sparkplug wire, making a little flag or tab. This part is important, since you don't want to finish the job and wonder where the wires go. Next, pull the sparkplugs and carefully observe the condition of each plug. Look for oil fouling, wet plugs, WHITE plug insulators, worn plugs and damaged plugs. If the center insulator (the part that goes INSIDE the cylinder) is too white, it's an indication that the engine is running too lean and you could be causing damage to valves or pistons. If the plug is black and oily, it indicates that the cylinder is worn and oil is leaking past the rings or valve stem seals. If the sparkplug is wet with fuel, it's an indicator that the cylinder is FLOODED, meaning that somehow there is too much fuel being delivered, and a wet sparkplug cannot properly ignite the fuel in the cylinder. If the plugs all check out ok, use a compression gauge while your friend again tries to start the engine. Since there are no plugs in the cylinders, the engine won't start, but you're measuring the pressure that is built up in the cylinders. Generally, it should be around 90 PSI, but that number may be different for different engines. Generally, the number should be withing 5 to 10 PSI for each cylinder. A variance of more than 15 PSI indicates burned valves or worn rings. If ALL cylinders are low, (below 70 PSI) it's a good indication that the camshaft is no longer timed properly. That is caused by a slipped timing belt or timing chain. . THE 'KEY' COULD BE THE ANSWER. Well... some recent cars/vans have a immobilizer embedded. Such a car/van can only be started with an original key i.e. a key which comes with the cars and which has a electronic chip. So if you have recently cut a key from any roadside key-cutter and your car turns using this key but the engine fails to fire it could be the immobilising safety device in your car that's preventing it from starting. This is a good safety feature! Another ting to try is removing the spark plugs (make sure you re- cord which wires go where) and pro vidind that the engine isn't flooded spray some starting fluid(avalible at auto parts stores) in the hol where the spark plug was and put the spark plugs back in and try to start it if it begins to start but then shuts off your problem is proboly fuel delivery, but if the engine is flooded take out the plugs and let it sitt for a while to dry out. There is a little sprocket in your strarter looks like a cog with teeth on in, but the teeth can chip or break if the metal is cheap which in most cars now days it is. So the starter is turning but the missing teeth are not connecting to make a spark keep turning it samething happened to my Buick but i didnt gte is fixed rite away because if you keep cranking evetually the teeth will catch and ignite a motor needs fuel/ spark / air / compression all at the correct time check sources of all from major parts to minor (id start with anything electrical) you should find the problem - One other thing that could possibly have gone bad is the main relay, its a $50 part that gives the fuel pump power when the key is on, so bad relay, no power to pump, no gas, no start. -you need, spark, compression and a proper fuel mixture for your car to start. Generally, the compression gives way over time, so it is the last thing you should suspect if this problem appeared overnight. First thing you should try is to turn the key to the "on" position (not the crank start position). You should hear an electronic hum coming from the fuel tank. If you don't hear the hum, check the fuel pump relay or fuse. If those are fine, the fuel pump is suspect. If you do hear the hum, your fuel pump is working fine. Check for fuel pressure in the fuel line. It should look like a valve like the one you might find on a bicycle tire. If fuel sprays out, your fuel pressure is fine, which means you can suspect the spark. The battery is not the culprit (it turned the starter remember). Check for spark as noted above. If you don't get spark, check spark from the coil. Depending on the model and technology of your car, you can then suspect the ignition control module (esp. if it was a hot day) , as well as the distributor and all its components like the rotor and distributor cap. By the way, most, if not all new cars have an inertia trip switch. Mine is under the dash. . (MORE)
You have to fix the problem causing it first. Find out what is missing. On some newer cars, it is easier to check for spark, than it is for gas. On other newer cars, it is hard to find out either, or, because of their lack of having high tension wires. What year/type car do you have? E-mail above.

Answer . Check your battery first, and if not your starter or ignition switch, after that, it's something more serious.
Why wouldn't a 92 RS Camero V6 Auto in the cold start when engine turns over it jumps with a weird intake noise but will not kick on?
Answer . Answer 1 ==\n. \nI'm not familiar with your make and model, but had similar symptoms on my Ford LTD a few years back. It was cranking, firing, acting like it wanted to start, but backfired out of the carburator, made weird "gurgling" sounds at the carb intake, and actually shot fire o…ut of the carb.\n. \nWhen I gave up trying to trouble shoot the problem myself, I called in a mobile mechanic, and he determined that the timing chain had "jumped time."\n. \nThe purpose of the timing chain, or timing belt on some vehicles, is to coordinate the timing of the valves now usually in the head(s) to the distributor and pistons.\n. \nIf the timing chain or belt "slips" or jumps time, then IF the intake valves happen to be open when the distributor fires a plug(s) the fuel is ignited, and the expanding burning fuel escapes back through the intake manifold, carburator, and air cleaner system. This is what causes the "weird intake noise" which you describe. \n. \nI suspect that this is the cause of your problem, and if I'm correct, it is a major issue, which will require replacement of timing chain or belt, possibly gear sprocket(s) or pulley(s), and also possibly other engine components damaged by the out of time cranking.\n. \nUnless you are a very good "shade tree mechanic," you need a professional automotive repair shop.

Your 1998 Chrysler sebring convertible lxi v6 wont start has no spark but turns over no previous problems just didnt want to start all of a sudden?
Dear distressed, had the same problem with my 1999 sebring 2.5 v6.Changed the distributer because i was told after running adiagnostic test that the problem might be the camshaft sensor whichhappens to be built in the distributer of the 2.5 v6 coupe model.After replacing still had same problem would… run for 5 to 10minutes then die, unable to start again till it cooled down. Turnsout it was the crankshaft sensor ($100) part and car is runningfine now. Each one of these sensors when they go bad shut downspark to distributer. Hope this is of some help considering i wasat my wits end by the time i figured it out. I had same problem with a 98 sebring coupe Lxi. ReplacedDistributor which had built in coil, lland it turned right on. Hopethis helps. (MORE)
Answer . You need 3 things to make every engine run. You need fuel pressure, good spark, and compression in the cylinders. Start with these 3 things and go from there. Hope this helps
Call the dearler...its probaly the purge control sensor!. Thanks....I had them replace purge control valve this past saturday...refueled last night and all was good
There are only three possibilities or any combination thereof: It's either fuel, ignition or compression. I know that doesn't give much information, and unfortunately, that's the best that anyone can do without seeing the vehicle or knowing more about the problems. Fuel delivery is a quick and… easy thing to diagnose. Purchase a can of starting fluid and spray it into the throttle body as an assistant attempts to start the engine. If the engine starts briefly, you have a fuel problem. The starting fluid has replaced the normal fuel and if the engine runs with starting fluid, everything else just checked out ok. At that point, check the fuel pressure at the pressure test port. You may need to buy, rent or borrow a fuel pressure gauge and while you're at it, see if you can figure out how much pressure you're supposed to have. Just slowly isolate the problem, one piece at a time and you'll get there. If the starting fluid didn't help, check for spark. Sometimes an ECM can go bad and you won't get any spark. If that's the case, you'll get a computer diagnostic code. In this case, buy, rent or borrow a code scanner for your vehicle and determine what if any codes are showing. The computer will tell you if it thinks anything electronic is wrong. Unfortunately, the computer doesn't usually tell us much about the fuel pump or fuel pressure, so good luck with that. you need to check your crank sensor it will not let spark to your plugs if it is not reading crank motion. It is located in front of the oil pan under the engine; cost about a hundred bucks and very easy to change (MORE)
\nNo car can start until it turns over. Meaning the starter has to engage. So you have at least one problem or more. You have to have a good battery and it has to be 12.6 volts and remain at 8-12 vol;ts while trying to crank. When you cut the ignition on - the instrument panel has to light up and wh…en you go to "start " you have to hear a soleniod in the starter go clunk. No clunk? There is a problem in the circuit to the soleniod. Clunks - but no turn over? Bad connection from the starter to the battery or bad starter. (MORE)

That my friend is the wonderful SECURITY system of GM, that little bump on your key has a resistor in it, when you put it in, if the security system doesnt read the proper value, due to various conditions -- worn contacts, dirty contacts, etc. This causes everything to work, except it will disable t…he starter and the fuel pump..neeto huh.. To test if its this is the case simply put the key in, try to start it and then remove the key, if you see a SECURITY light on the dash lit up after you remove the key, then that is the problem.. it will wait 3 minutes before the light goes out and you can try again.. The cheep fix for this is to buy a remote start kit from Kragen, as it simulates the resistor that is in your key -- they go for 24-40 bucks, lot cheaper than going to a dealer to have it fixed, or taking your steering column apart ...

There are many causes for no start; fuel pump: check fuel pressure, Timing belt; remove top timing belt covers and check timing marks, engine must be set to top dead center(line up timing marks on crank shaft pulley and timing cover), PCM fuse blown. I had the same problem with my 99 Cirrus. I was d…riving mine when it sputtered out and wouldn't restart. After checking the timing belt, fuel pump, & crank sensor, I ended up replacing the distributor. The process is relatively simple, but with tight clearances, and problems with tools and corroded screws/bolts, it ended up taking about 4-6 hrs. The dealer quoted me $1200 for parts and labor but I was able to pickup an OEM distributor off eBay for $200. Well worth the time and effort to save a grand. (MORE)
Battery has enough to turn the engine but not enough to provide spark at the same time. Confirm by jump starting.
If the motor turns over then start by checking for fire at theplugs. Check to make sure that the timing belt is not broken and isworking properly. Check the cam and crank sensors for properoperation, as well as proper fuel flow.
There are way too many answers availalbe here to give you just one.. You need three things to make your Jeep run.. Fuel - make sure it's getting fuel to the pistons. Air - air cleaner clean?.

\nThere are 2 problems listed but only one most important so far. The engine can't start until it gets turned over by the starter. You have to have a hot battery, good battery cable connections, a good starter relay and a electrical circuit from the inginion switch and other circuits to the relay.
approximatly $545 and it takes about 6-8 hours if you do it yourself and take your time 10-12 hours and the kit is worth 69 dollars and includeds all the necessary gaskets there are great websites with pictures that show exactyly how to do it and they are very informative also good luck
Why does the starting solenoid just click on a 1986 Ford Bronco V6 when you turn the key and it doesn't turn over the starter I have replaced the starter the starter relay and have a new battery.?
I would start by jumping the terminals on the starter solenoind,just use a wrench and touch it between the two large terminals on the solenoid. If the starter takes off and works I would guess that your problem may be in the ignition switch located on the steering column.. Sometimes even though the… battery terminals look clean and the interior lights still light up, they can need cleaning. It is also possible that the wire into the terminal is not getting a good connection. This seems elementary, but it is the an easy solution and in my experience, this is most often the problem.

I have a 2002 Malibu LS V6 that turns over about 4 times then starts After that it runs like normal when idle or driving. It's not the battery what could the problem possibly be?

I have a 2002 Malibu LS V6 it turns over about 4 times then starts. After that it runs like normal when idle or driving. It's not the battery so what could it be?
If the check engine light is on then you need to have it diagnosed. If not then replace the fuel filter.
Several possibilities come to mind: . no gas in the tank or blocked fuel filter . bad or missing spark plugs and/or plug wires . engine timing . broken/slipping timing belt

When this happens, it's usually down to either an electrical problem, or the fuel system. I would advise checking the ignition system first. Start by removing the spark-plugs, get someone to turn the engine over on the starter, whilst you check for sparks at the plugs. It's always worthwhile to c…lean and reset the plugs at this time. Also check the appearance of the central insulator, if its a light greyish brown colour, then you fuel system is correctly set, thus unlikely to be the source of the problem. If, on the other hand its a sooty Matt black colour, check your air-cleaner, this may be clogged and will need to be replaced. An oily, gloss black colour, usually indicates a worn engine, this will need to be overhauled or replaced. If you happen to notice a strong smell of gasoline, your engine has flooded, this will probably have drowned the sparks at the plugs, causing your starting problems. You will need to dry out the cylinders by turning the engine over on the starter, before reassembly. On a significant number of cars, produced in the last 20 years, the ignition system is preset and not adjustable. However, if your car has an adjustable ignition system, it's worth checking these settings, before trying to start the engine again. (MORE)

1997 Chevrolet c1500 vortec v6 has not been started for 4 years new fuel pump gets fuel to carb tries to start but will not any ideas?
The three main factors in an engine being able to run are: fuel, air, and ignition. If your vehicle has been not been started in 4 years, you need to check all the possible sources, and start out with the basics. Check your spark plugs, if they look corroded, clean them up and put em back in. Tip: p…ull the plug wires off and let em just barely hang on the the plug, this makes the coil hit harder and can tell you if you have bad plug wires. Next, you say that it has a new fuel pump. I hope the new fuel pump is OEM or altleast meets OEM specs, because a number of aftermarket cheap fuel pumps just don't put out the pressures the system reqires. Tip: Try turning the key on and off and listen carfully for the fuel pump to turn on and off, do this 5 times or more and then try to start it. Do not continueously turn the engine over for more than a few seconds, all this will do is kill your battery and potentionally burn the brushes in the starter. I have a 2000 Chevy blazer with a Vortec V6, and I've had this same problem before. On your vehicle there may be fuel line toward the rear of the engine close to the fire wall, that has a red nipple over the pressure testing valve. This is a small valve with a regular stem just like any air stem valve. Try depressing this valve with your finger and see if you can relieve the system of any air and maybe a little too much fuel. Then try starting the vehicle. I did this after I installed a new fuel pump and after running in to the same problems, and I was eventually able to crank up. One more thing, since the vehicle has been setting for 4 years, check the in line fuel filter and make sure that it isn't plugged up with goop or rotted out inside. If it were, surely it wouldn't run. For anyone who else might ask, think about the environment the vehicle has been set up in, was it possible for rats or birds to possibley make a nest in the intake or intake manifold. I once pulled a small engine apart and found 3 dead burned up mice in the combustion chamber. (MORE)

Check to make sure you have gas getting to the carburetor and spark on the spark plugs. Make sure the fuel selector is on and there's sufficient fuel in the tank to reach the pick up. If you have gas and spark and the engine still won't start, you have to start looking for a problem. Start with m…easuring the compression in each cylinder. There are a lot of specifics depending on what kind of jet ski you actually have. For example, if it's fuel injected, there's one set of procedures. If it's a 4 cycle, the steps are different from a 2 cycle. Usually, the owner's manual or shop manual will have troubleshooting steps. (MORE)
How difficult is it to go from a 1991 Blazer S-10 carburetor 4.3L V6 to the 4.3L V6 vortec in the 1993 Blazer S-10?
You have to change from the block up including the heads, intake, Computer and wiring.
Commonly a fuel pump issue. An easy test: Have someone bang on the fuel tank as you try crank the engine. The engine could be flooded with gas, or there could also be an ignition issue.
Use crank bolt to turn engine so number one cyl at tdc. You can feel it move up through plug hole with a helper. Then use mark on balancer to set zero. Then you drop it in, but the tricky part is rotor has to be in position to fire number one terminal. See below for more details.
