Your '95 Neon starts and runs fine while engine is cold after engine has warmed up to normal operating temp it stalls out and will not restart until engine has been allowed to cool down again.?
Answer . \nCheck the coil pak. Known to do this.. Answer . I own a '95 Neon that is doing JUST THIS SAME THING! Today I decided that I would change the ignition coil, but oddly that DID NOT solve the problem. I'm exactly sure what the problem is now....any other ideas???. Answer . \nIt is… a ECT sensor problem. Im positive. Answer . \nya, check the sensors if changing the coil pack did not work.. Answer . I find that ignition modules are more apt to have the problem described, coils are usually consistent.\n. \n. \nI agree. If the coil checks out OK, then the ignition module, attached to the distributor, cuts out at a higher temperature.. Answer . \ni have a 1996 neon it is doing the same thing. I got the ignition coil replaced, didnt work. a complete tune up, didnt work. recently had the throttle body cleaned, didnt work. i think (MORE)
Sunfire surges after starting up but runs fine after the 1st block When first running it seems to surge and then when you start to drive it it seems like it has no power then will lurch and run ok?
Answer . The first thing that i would check is the t.p.s which is the throttle position sensor, if it is sticking, or shorting out, it may cause the problem you stated.
On A 1999 Tahoe it wont start on cold days without a shot of starting fluid but it runs well and starts fine when warm you have replaced coolant tempand intake air temp semsor theconnollys1netzerocom?
Answer . \nSounds too simple to be true but check your battery and bat. cable connections. You need all the cold-cranking amps you can get.

Answer . \nIf it looks like a duck and tastes like a duck, it might just be a duck. Sounds like you need a MAF sensor.
What could be causing 1996 buick riviera to die while driving down the road normally starts right back up and runs fine - when engine dies its approx 15 min from cold start no codes?
Answer . Most common problems are Crank Sensor-cheap part, hard to change. Or Ignition Module-expensive, but easy to change. . I have a 98 Riviera stalling out at coast or down hill. Chevy Dealer/Service $70 Diagnostic Vacuum harness, had to order so they taped it off as I drove away and started …to accelerate the engine started to miss going uphill. Changed Vacuume harness not stalling anymore. Dtc codes 101(air) and 341(crank). Changed mass airflow sensor and crank shaft sensor. Still miss. Changed coils. Still miss and sputter under high accler.. Answer . Could it be a bad ground? I had a Bonneville that would die going around corners. Turned out that when I turned the wheel a certain way, it would die out . Check the engine knock sensor. I've seen it cause that on a few other v-6 GMs. (MORE)
Fuel pump will not come on sometimes engine never quits running after its started but wont start sometime fuel pump has been replaced?
could be a bad case of run-on as i had prob. was bad idle adj... check idle/injectors/sensors Sounds to me like he is saying that the engine runs fine after started not that it has a run-on problem.
What could cause problems with starting when the truck is warmed up but starts fine when it is cold?
Answer . It's something in your fuel line. Maybe your fuel pump or the filter. . could also be your starter getting old and also maybe getting too hot
1993 dodge caravan 3.0 v6 and after it warms up and you drive it for awhile you try to restart it but the it wont start the engine cranks but nothing you replaced the fuel pump already?
is the van getting spark? does the fuel rail have fuel pressure Might want to check your knock sensor if equipped
Why in the morning starting 1995 Camry 4 Cly you have to press on the gas pedal to keep it running ones it warms up it runs fine?
Answer . \nTypically it means that the engine is running too lean. \nLook for a vacuum hose that has cracked or popped off.\nPut a small piece of tubing to your ear and wave the other end around any vacuum hoses inside the engine compartment to listen for a hiss.
Why does your 03 xterra wont start back up or turn over after driving but will start back up anywhere from 45 minutes to 5 hours?
You need to reprogram your key to the car vin.. The dealer knows about this... Enjoy the xterra
check fuel preasure, first I would check fuel preasure,second I would make sure the exhaust isn't plugged causing back preasure. You didnt say if you have a check engine light, also check for vacume leaks or disconnected hoses.You should also check the Mass Air Flow (MAF) sensor to see if it is dir…ty or defective. If there is corrosion on the diodes this can usually be cleaned off using some electrical contact cleaner and a toothbrush. Becareful not to use too much force when cleaning or you will break the elements and will then need to replace the MAF sensor. I recently (May '07) replaced one w/ a unit from a local salvage yard and the price was $35. A new MAF sensor for this Make & Model will cost you around $100.The fuel filter is something else you can check if you have low fuel pressure. If you do have a check engine light coming on I would take the car to one of your local auto parts stores and have them check the code(s) for you. Most automotive parts stores will do this as a free service. (MORE)
Answer . The grease in the ignition becomes 'frozen' in the colder weather. When you insert the key and turn, it triggers the anti-theft system. The 'solution' to this problem is to keep a lighter in your car and heat the key up BEFORE you insert and turn to start the engine. If you trigger the a…nti-theft system, you are going to have to wait 10 minutes for it to reset.. Another problem could be in the ignition switch The switch contains the anti-theft logic and is suseptible to moisture This is a very common problem. If your security light flashes when it won't start it's your problem for sure Also if you have the codes checked it will have B2960 and B3033 in the body control module history (MORE)
What could be the problem if your 2000 s10 w4.3 wont start when cold but runs fine when even a lil warm?
\n. \nThe engine coolant temp switch could be a possiblity.If I give it a little gas with foot on brake it does not hesitate and the fuel is running very rich
Why would a 96 Tahoe start good cold but not when it is warm you smell fuel bad you have done a tune up and replaced map sensor ecm and it pulls miss fire code and wont reset?
Keep in mind the #1 problem with these vehicles is fuel pumps. As the fuel pump gets weak it can still allow the car to run but, it will have starting problems like you mentioned. Have the pressure tested. Sounds like broken fuel pressure regulator. it is loccated on driver side of engine with vacuu…m hose to it and a clamp similar to ac hose connector clamp. If diaphragm is broken in this regulator it will allow raw gas to "flood the engine" when the engine is warm. When the engine has time to cool, the extra gas evaporates. (MORE)
Why would a 2002 ford Taurus run fine when you start it but after it warms up and shut it off then start it again it begins to die or sputter?
Answer . \nIt COULD be a weak fuel pump. I have had a similar situation. In my case all I had to do was turn the ignition to RUN not start and let it sit until the pump stops humming. After the pump stops humming,then start the vehicle.
Why wont mine 1989 Honda accord lxi start after you shut it off after its been running get warmed upit fires up in morning just fine and after it sits all day runs fine?
My 89 LXI did the same thing for a while until one day it woudn't start at all. After testing found a faulty rotor. After replacing rotor, it hasn't happened again. I'm no expert but i have noticed when it wont start i just open the gas cap to release the pressure then it starts, when warm.
Mass Air Flow Sensor . I have a 99 Jetta with exactly the same problem. I don't have a definitive answer but I am being told that it is a problem with the Mas Air Flow Sensor, which needs to be replaced.. Likewise, I had CEL on and error code 1128. Fixed it myself in about 10 minutes. Went to Sc…hucks, removed MAF sensor, bought one there for $84 and gave them the core, reinstalled in parking lot in about 2.5 minutes, reset the CEL with their complimentary code reader usage, and passed emissions the next day after the drive cycle. Easy fix. Don't let the shop get $400 out of you... (MORE)
1989 f250 runs fine until warm then starts to miss and finally dies most sensors have been replaced and also the coil and computer could the problem be in the distributor?
Answer . the ignition controle module is mounted on the side of the distributor, this is most likely the problem. When it cools down it should start and run fine. To replace this you will need some small sockets, poss. tourqes sockets. Good Luck you might check your fuel psi when it is acting up… to rull out that. If its low try the filter first, then the pump. Psi should be at 30-45 psi with 6 ounces of fuel for 5 seconds of pump run time. (MORE)
Check the cars ignition coil and crank sensor. Either of thesecould be overheating and causing the car to not start until it sitsfor a while.
What would cause 1995 3.8 V6 Pontiac Transport to idle fine when first started but after warming up will start to pop when idling and shudder while driving I have replaced EGR and TPS?
try checking the oil and the tires if you have not already tried this or check the gas filter
I am not sure of the type of car. I had the same problem with a Chev Beretta. It would not bring up a computer code so I tried different things without success. I changed the computer and it fixed the problem and is doing fine. That worked for me. Anyway good luck
It will be alot cheaper to go to a repair shop and have them scan it for codes than to guess and spend money on parts you do NOT need.
Skoda 120LS wont start but will when bumped then runs perfect but wont restart until its fully warmed up any ideas have been advised could be hole in petrol pipe?
If the starter motor works ok and during start it turns the engine the the problem might be in overal setting of the engine. 1) Spark Spark might not have the sufficient power to start the engine. When bumping, you dont need power for starter motor, so then there is more power for ignition. Chec…k wheter the spark is strong, blue. Weak yellow spark indicates a problem. Wrong or old spark plugs, ignition cables Ignition distributor - gap on "spark making hammers" not properly set, or the "hammers" damaged - http://www.skoda110r.cz/gallery.php?aid=125&pid=1 - see point D http://www.skoda110r.cz/article.php?id=125 - use google translator to understand better Capacitor may be damaged Pre-ignition wrong set Grounding of the engine insufficient - check grounding strip on the engine and on the battery (-). Also contact between the engine support bar and body Ignition Coil - Measure its resistance and compare to other, if broken, needs replacement. 2) Fuel I saw a hole in petrol tank, but I think it wouldne cause the problem with starting Reasons might be: Carburetor choke not working properly - operating string might be loose Carburetor top cover might be bent therefore not sealed well - more air is going into the system than required Recommendation Buy new spark plugs, ignition cables, capacitor, distributor head and contact. Set gap on the hammers (preferably buy hammers new as well), set preignition, make sure grounding or the engine is good. If this doesnt help, then service the carburetor at some specialist. hope it helped www.skoda10r.cz (MORE)
89 Chevy Corsica runs fine until it warms up then bogs like its lost power but will still work Just recently sometimes like 1 out of 10 wont crank right away Have to pump the gas to start.?
You have the classic symptoms of a bad coil pack! Have been thru this about 6 times in the last 8 years. Check them. Could also not hurt to check fuel pressure/fuel filter
Why does my 1990 Plymouth laser rs runs rich miss all the time after it warms up and you cut it off it wont start back?
you may need a new speed idle control value or your engine has a problem.. you may need a new speed idle control value or your engine has a problem.
Overheating ? - Check radiator for water and coolant, and engine for enough oil and not old burnt oil
What happens if your 97 Camry starts fine but wont idle on its own you have to keep it at a contant idle for a minute or two then it starts to idle on its own and after its been running it wont do it?
The issue may be one of several things. It may be caused by aclogged fuel line or fuel filter. There may also be a problem withthe fuel pump, or a hole in the fuel line. It may also be caused bythe fuel/air mixture being off.
You have a 1991 ford e150 van with a 350 and when you first start it up starts fine the 2nd time you start it up befor an hour goes by it wont start you have replaced the battrey and spark pluson it s?
I had the same problem on my 1988 and would have to leave it on. On that motor, there is a heat shield that surrounds the starter and if it is not there, when the motor heats up it will transfer that heat to the starter simulating a bad battery/starter problem. Once it cools down it starts fine. Sta…rt looking from there or get a remote starter (like I did) so you can leave it running when you run into somewhere fast..

It is most likely the fuel pump main relay. It is a very common problem on civics.
C 1500 Chevy runs rich after warm up Starts and runs fine when cold. After warm up runs rich throttle bogs and puts out black smoke like it's being choked.?
sounds like its a carbureted truck id blame the carburetor for the problem most likely the choke is sticking or the choke control is not working. typically there is a spring like coil that opens and closes the choke based on engine temperature (the throttle plate on top and the linkages connected to… it and so on should be inspected) . ive seen a faulty idle air control solenoid on fuel injected vehicles do various things including this (MORE)
Check the coolant temp sensor. The one for the computer not the guage if so equipped
Why wont your 1998 Saturn SC2 start It turns over fine but wont start and has been running rough when first starting i also smell fuel strong when i try and start it?
Most likely your coolant sensor is reading incorrectly and causing too much fuel to be injected as the PCM thinks it's colder than it is. Unplug the sensor and check for corrosion on the connector
What would cause a 1994 to start and run fine and then not start I have replaced the coil with no success.?
Did you check to see if theres any spark from the plugs after it wont start... if no spark check to see if the coil is getting power, if not then check the ASD Relay on the fender near the battery. Theres like 5 relays there... The ASD relay cuts power to both the Coil and Fuel Pump.
1999 Jeep Cherokee quit running and am getting a code that says no buS. Engine will not start Fuel pump wont come on and gauges don't work. I replaced ECM and it did not help. Now What?
Found the problem. OBDII gave me a fault code. P1694. It was the Crankshaft Position Sensor. The sensor was shorting out which caused the gauges to not function.
Car wont start in the morning when cold but will in the afternoon when it warms up Battery has been replaced Wont even turn over. I dont mean cold like zero weather..I mean like 30-40 degrees.?
Could be several things, First try a few shims between the engine and the starter, if that doesn't work, change the starter. Just a suggestion.
the starter may be worn on your car if it starts up easily when its cold but slowly turns over when it is at the operating temperature. Replace the starter to your engine.
While driving your 91 3.1 it will start to run bad and the speedo will drop to 0 then kick back in and run fine no pattern when it will do it and there are times it wont do it at all1991 lumina 3.1?
Clean the ground connection at the transmission from the battery negative lead. Take apart, use sandpaper to make metal bright and clean, reassemble. You seem to have an electrical ground problem.
It could be something to do with you spark plugs/wires/distributor. and on alot of GM cars and trucks it could be the fuel pump. The best thing to do is take it by a TRUSTED mechanic to check it out.
1991 camaro wont restart after warm up in close loop no injector pulse at cranking rpm has spark and fule pressure is normal ecm tps map iac all confirmed ok will start with fule added at air intake?
no injector pulse only after warm up sounds like an electronics problem. ive seen many computers that were faulty that had no codes . it could also be the prom chip. try replacing the ecm and injector fuses.
try replacing the black coolant thermistor located on the back of the thermostat housing this maybe tellin the ecu that the engine is warm rather than cold causing problems starting when cold
2002 ford explorer and it runs fine then you shut it off and it wont start back up for like 8 hours?
we have put on altenator, spark plugs, spark plug wires, battery, starter and the relay looks good and nothing has fixed the problem
1990 pick up it starts fine first time after a few hours driving if you shut if off it wont start why?
I had this problem in my 1990 Ford F150. The battery cables were bad and weren't carrying the charge from the alternator to the battery
The coolant temperature sensor is usually bad. It tells the computer that the engine is cold and to give extra pulses to the Fuel Injectors to make it rich enough to fire. Much like the choke function in older cars. This sensor is located on the thermostat housing, drivers side front, on the top of… the housing. I has 2 wires. Part sells for 17-32 dollars. (MORE)
My 04 accord runs fine after I replaced starter with the remanufactured one. But every time after I drive it for a trip then it will not start. The Car only starts when the engine is cold?
Sound like your fuel pump relay is going out. i had the same problem same time ago.
I've had the alternator checked and replaced the battery so why will my 2002 Chevrolet Silverado will start up fine but won't keep running?
Engine Stalling Issues Without doing a personal, onsite, troubleshooting of your vehicle, NO ONE on here can precisely identify the cause of your problem. However, the symptoms you describe suggest that the problem never was related to the electrical/ignition systems, BUT INSTEAD... It sounds like… you have a "fuel starvation" issue. Usually, when an ICE [internal combustion engine] will start, but then dies [stalls, whatever you want to call it] after only a short time of running, is an indicator of a flow problem in the fuel system. The fault causing this could be located anywhere in the system from the fuel tank to the carburetor or fuel injection system, whichever your vehicle has. My first "guess" as to cause would be a "partial" blockage in the fuel delivery system, which is not limited to but would include items, like : . A clogged fuel filter , or filters, . A clogged fuel pickup filter screen inside the fuel tank, . A "pinched" or partially collapsed fuel line , . A partially clogged passage inside the fuel pump, or pumps, . A partially clogged passage inside the carburetor, or fuel injection gallery, or . A partially clogged passage inside of, or a defective, fuel tank selector valve [not the switch on the instrument panel, but the actual valve]. These are the possible causes I can think of at the moment, but there may be others. The only solution is to troubleshoot the entire fuel system, find and identify the fault, and properly repair the fault, or replace a the defective part if it's unrepairable. (MORE)
My 1989 Chevy 305 van runs fine till it warms up then stalls out runs poorly and will only start at full throttle?
Sounds like vapor lock. The fuel in the line to the carburetor is vaporizing before it enters the engine.
Hi, I had the same problem with my car just after I bought it. It's an older model with a carby. I was told because of the heat of the engine it makes it harder to start the car after it has been driven at normal operating temperature. You shouldn't have trouble jump starting it, or just give it a l…ot of gas when you are starting it after driving. If you have a carburettor, you have to be one with it. Hope this helps (MORE)
I have a 95 cavalier auto trans and out of nowhere it wont start. replaced starter and still nothing but when i jump it with a screwdriver it starts and runs fine. any suggestions?
Neutral safety switch out of adjustment or the shifter cable out of adjustment.See if it will start in any other gear.If it will one of those are the problem,my guess is the cable out of adj.
Why would a 2001 dodge ram 1500 sport being running fine until it warms up than start shifting rough?
bypass the the line that runs into the radiator. witch is a trans oil warmer. reconnect both lines together
What is it when the car is cold at starting up it wont drive or back up but when your car is warm it runs perfect?
Your car has to achieve operating temperature before it functions as it should. Your heads which contain your valves are cold and don't move as easily as they do warm. This is why your thermostat doesn't open up until it reaches either 185 or 192 degrees. If you have a cold-blooded engine, you have …to wait for it to warm up. You can quicken the process by revving the engine slightly. If your car is not cold-blooded, the best way to warm it up is by driving it. If your'e engine is taking a long time to warm up, your thermostat may stuck open, causing the antifreeze to cool the engine before it is even warm. Hope this helps (MORE)
