04 Isuzu diesel truck will not shut off when key is off?
check engine shut off electronic valve on injector pump -most likely valve is stuck or fuse is blown -use a test light to check for power at the switch on the pump when key is turned on -to clean valve u need to remove the electrical wire with 8 spanner then undo solonoid valve located at the back top of the injector pump -usually a 25 or 27 mm. spanner will fit -make sure u dont loose the the poppet valve or spring and o ring when removing --when its out you can test on a 12v or 24 v depends on truck voltage - battery with live on pin and earth on frame of valve -valve should pull in when given power-

In recent experience, I have learned that a 1992 rodeo does not have a cut off switch and that on most the fuel pump is in the tank!
most likely cause is the timing is advanced too much and isnt shutting off properly
Answer . one of the main reasons an engine runs on or diesels can be related to the fact that it is idling too fast. Set the idling down and see if this imporoves
Answer . \nwhat kind of car? IF its fuel injected the key turns off the computer, the fuel pump, and the ignition coil
Answer . \nOn a carburated vehicle the power to the distributor and coil is cut off when the key is turned off causing it not to fire.
Run-On . \nThis condition can occur for a multitude of reasons:\n. \nBuilt-up carbon in the ignition chamber can glow red after the engine is off, providing a mechanism for sparking unburnt fuel. Such a thing can happen when the engine runs very rich, depositing unspent fuel and particles on the… pistons and valves. Similarly, non-smooth metal regions within the piston chamber can cause this same problem, for they can glow red. Also an improperly rated sparkplug can retain heat and cause the same problem. \nHot vaporized oil gases from the engine crankcase can provide ample fuel for dieseling. \n. \nIncorrect timing. \n. \nAn engine that runs too hot or too lean may produce an environment conducive to allowing unspent fuel to combust.\n. \nAn idle speed that is too fast can leave the engine with too much angular momentum upon shutdown, raising the chances that the engine can turnover and combust more fuel and lock itself into a cycle of continuous running. \n. \nPotential fixes\nI suggest you run a can of Seafoam Engine Treatment through a full tank of gas. \n. \nFor those engines that run too hot or too lean, verify that all mechanisms in place to cool the engine properly function as they should. Replace the thermostat if necessary. Clean the radiator. Verify that all auxiliary fans engage at their proper temperatures, and ensure that the thermostatic sensors on belt driven fans engage as necessary.\n. \nIn the case that there is too much angular momentum, lower the idle speed if possible or at lest have the idle speed motor checked out. Good Luck! (MORE)
Answer . \nThis can happen in the older GM trucks and cars (the ones with 2 different keys, square for ignition and round for the door). There are a couple of different ways this can happen. Either the gear at the back of the lock has broken (or come loose) or there is a part further down in the… steering column that also can break that would cause this symptom. Some call it the "rack" because the dealers replacement part is called a "rack kit". (MORE)
Answer . Possible causes are a fulty horn relay, faulty horn switch (probably part of the steering wheel SRS module), or a short circuit between the horn relay & horn switch. Quickest temporary fix is to remove the horn relay, but as a horn is part of the required safety equipment on automobiles… you need to find the source of the problem & fix it asap. (MORE)
You can disconect the battery, which i wouldn't recommend. This means the engine is still spinning, and might still be drawing fuel, but it wont be using the fuel. This will either break something outright, or eventualy lock the engine, where you will be unable to turn it over. I would recommend tha…t you put the car in Neutral, hold the brakes, and simply let the engine idle away the gas. Or you can do something to interrupt the flow of gas, IE put a really big clamp on the fuel line so that it runs out of fuel and stops spinning. NEVER YANK THE FUEL LINE OUT! you will get sprayed with gas as the pressure equalizes, and you will look really dumb at the ER when they ask how you messed up your eyes. Then get it to a mechanic as soon as possible, because that is going to be a really big electrical problem. (MORE)
Won't shut off or you just can't remove the key....there is a small hole located under the steering wheel, if you push in a small screw driver or possibly a pen or pencil in this hole and this will manually releases the key. there is a solenoid that is suppose to actual the key release when you shut… off the car. Problem could be selenoid is not working or... as in my case the wiring harness for this, is located inside the shifter console was broken. This wiring pigtail powers this and other safety features. Poor design by GM as the wires bend back and forth with the shifter... so over time the wires eventually brake off of the connector. A new pigtail is about $50 Wow so I suggest carry around the pencil or pen for when this happens. (MORE)
Answer . Mine pings also. It's the heat shields that help protect the engine against the temperatures of the catalytic converter and muffer.\n. \nHope This Helps.
Answer . could be many of things. debris in fuel tank, looses vaccum pressure,dirty fuel filter, dont know what kinda truck you got but most likely its a fuel blockage some where
Answer . I'm going to wing this and say first make sure you are in park. You may need to hold the brake pedal down to do this. If you are in park, just try to push the shifter a little further into park while turning the key off. Let me know how you make out. Hope this helps.
Shut off solenoid is located on the fuel injector pump, near the round diaphragm at the tip of the pump, towards the firewall. There is one white wire (usually white) that goes to it. That is the only electrical connection on the pump. The solenoid iteself is round, with a small male electrical blad…e connector on the end of it. It unscrews from the whole pump for replacement.

1995 E350 diesel Engine shuts down intermittently. On The 7.3 what causes the engine to shut off when you turn the key to the off position?
The reason the engine shuts off intermittently is probably a crank position sensor, this is an electronic part which mounts on the front of the engine. When this goes bad the engine will sometimes just not work, or will work sometimes but then just dies. Fuel shut off is what happens when you tur…n the key off. The power to the fuel pump is cut which ends fuel flow to the engine. (MORE)
Your diesel vehicle might keep running after turning off the keybecause there is still enough fuel in the system to allow it toidle. In many diesel vehicles, the engine is stopped by choking thefuel.
Answer . fuel cut off valve not working, to shut a diesel off all you have to do is cut off the fuel,
You have to replace a relay switch for the wipers this sholud be found under the hood in the engine compartment fuse box.
There could be a short in the wiring if a 1990 Ford diesel startsand then shuts off after 30 seconds. The short could be a hot shortwhich causes the wiring to get extremely warm and then short outcausing the engine to die.
If your key will not turn off your car alarm at drivers door lock cylinder, remove drivers door panel, and check the rear of lock cylinder for a switch which should be attached to back of lock cylinder(often can be knocked off when door has been opened using a slim jimmy), if not attach, re-attach, …if attached, then replace switch. Otherwise use key fob. i had a Nissan and i had to place the key in the passenger door to tun it off. i also had another Nissan it turned off by the trunk in the key (MORE)
The fuel shut off switch is designed to cut power to the fuel pumpin case of a collision. It is located under the dash on thepassenger side behind the plastic cowl shield.
When the key is turned off and the engine continues to run normally it is probably an electrical problem like a bad ignition switch. However, if the engine is "dieseling" and the ignition is really off, then the problem may be a buildup of carbon deposits on the tops of the pistons and the head and …spark plugs. You might try cleaning or replacing the spark plugs, then use a higher octane gasoline. But to simply stop the dieseling just turn off the ignition with the transmission in 'drive', then shift to 'park' after the engine has stopped turning over. The timing is too far advanced. Take it to a shop and find out why the timing is so far above top dead center. (MORE)
your better bet is go to the library and check it out , i know on the 1989 amigo you take the INSTRUMENT CLUSTER out and change a bolt from one place to a another and put it all back and the light goes off
The shut off electric solenoid is located on the very front of the engine, just above the fuel injection pump.. If you look at the front of engine looking back it will be on your left.. Bud
usually to cause an engine to diesel when shut off, the spark plugs are dirty or burned out.also check the timing
A 1986 Ford F150 starter won't stuff off when the key is turned offif the ignition switch is jammed. This will cause the start signalto be sent to the starter continuously.
If your truck is dieseling or running on, it could be that the fuelis too rich. Try using a lower octane of fuel.
check your relay and blue wire first. there may be nothing wrong with your solenoid at all
Repair the brakes. The light can be set on by a variety of problems from a burned out tail light bulb, to an unsafe condition such as stuck emergency brake shoes, or air in the lines, a bad sensor, or even the ABS module is bad.
The alternator light goes out on starting the engine when both the ignition source, and alternator are producing positive voltage. When the ignition switch is turned off, the engine, and of course, alternator are still turning momentarily. The alternator is then still producing positive voltage, whi…le the 'off' ignition switch has assumed a negative state, creating a closed + - circuit, allowing the lamp to light. This is a very normal state, and has occurred for many decades, even back to the days of cars running generators, prior to the alternator. Absolutely nothing to fear. (MORE)
Type your answer here... my areins snow blower wont shut off after it turn it off what could be the issue? Most of the time either your ground wire has broke off or the pin on the key barrel is rusty: Depending where your swith is located you have to get to the back of the key barrel to see if th…e wire is off there if it is not take a battery powered test light put the one end on the terminal where the wire is hooked to the key and put the other on a ground (clean bare metal) then turn the key to on position the light should be off turn the key to the off position the light should come on also try taking the key barrel out and clean spot where it sits and get some rust remover to clean it with. If this works pull the cover off your fly wheel put your test light on top of the coil and the term anal behind the switch if you get no light the replace the wire. Hope this helps (MORE)
Headlight power is not controlled by the ignition switch or keys. Damage to the turn signal lever could cause the 'flash to pass' circuit to stay on. Damage to the light switch could also cause the lights to stay on.
It could be one of several things. I am assuming it is the 6.5 litre turbo diesel. Your starter motor could be out of alignment and need adjustment. Another thing is the starter motor and/or celonoid could be bad and need replacement. Any number of things could be wrong with fuel systems and intakes… sytems where the truck is being starved of fuel or air and wont start.. obviously, you didn't read the question or comprehend it. The person who wrote the question stated that the engine turns over, hence the starter/ SOLENOID is working! One question does come to mind, do the glow plugs work? That may or may not be at the heart of the problem. The second question that comes up is, fuel delivery. Is the fuel filter clean enough to pass enough fuel? Any other fuel restriction issues? Just some things to look into for starters . (MORE)
Hey, Maybe you should check and make sure your key tumbler is actually working...If not replace it. Also make sure your ignition cut off wires are not cross shorted with another wire. Hope this helps. God Bless.
Change the wiper motor. There is a cam on the output of the wiper gearbox ( part of the motor) that shuts off the wipers when they reach the parked position. Yours is worn, never opens the internal switch, and the wipers just keep going. To just make them stop, unplug the electrical connection …on the wiper motor. The motor is on the firewall, above the engine, and not too far from the brake fluid reservoir. It's mostly aluminum colored, and about the size of a burrito. Probably four wires on the plug. (MORE)
Yes but off road diesel is usually highsulfur and may cause you some injector problems over time. Very hard to find but look for low sulfur off road. The only physical deference between low sulfur off road and low sulfur on road is a die that is put in the fuel causing it to be red and more easily d…etected when checking fuel for tax evasions purposes because you don't pay hwy tax on off road fuels.

I'm assuming this is a diesel. These engines have mechanical injection pumps and will continue to run indefinitely without "ignition being turned on" -- unlike gasoline engines which go off when power to the spark system is cut off. There is usually a grounding system connected to 'key on' whi…ch shuts off fuel to the injection pump when the key is turned fully off. I do not have wiring diagrams at hand, or immediate access to my 1999 NPR to check precisely how that is done on this truck, but I would check back to determine which component of the shutoff is dead or disabled. If there was a pre-existing issue with the truck not STARTING, particularly if there is some kind of anti-theft system acting on the fuel shutoff, and someone fixed that by disconnecting the shutoff, you may have an easier time determining where the problem is. You can always shut off the diesel engine by interrupting the flow of intake air -- I do NOT recommend you do this with your hand! -- and this should not cause any subsequent problems with restarting the engine again.

Place key in ignition and leave door open. Chime should be sounding. Get under the dash and see if you can find the source. It is likely a plastic or metal can near or in the fuse box. If so pull it out. Make sure the ignition still works after doing so. Otherwise it is in the dash and you may have… to disassemble it if you cannot reach it well enough to Disconnect its wiring. Do not irretrievably cut or break something since the ignition, door warning, lights, etc. may not work after disconnecting. Also wrapping it in sound proof cloth (or dipping it in commercial rubber dip) may be best bet. You really don't want to lock your keys in the car. (MORE)
The engine cooling fan will continue to run because the engine is hot. Once the engine has cooled down the fan will shut off. If it never shuts off you may have a bad temp switch or relay.
It could be a carbeuration or timing problem. A tune up should clear up the problem.
Today's vehicles have computers with all sorts of sensors. A broken wire or a wire with bad insulation can send bad information to the computer. A broken sensor can send bad information to the computer. Check for a bad wire. Check all fluid levels. If you can't find it, you will need to hook it up t…o a computer while you drive down the road and have the computer find the error. (MORE)
Most likely a worn electrical ignition switch. There is a steel rod that runs from the key cylinder to the electrical part of the ignition switch. As you turn the key the rod is pushed down and activates the different areas of the electrical switch. The switch is usually mounted on the top of the st…eering column with four small screws. It also has some amount of adjustment. It's possible it is just loose and/or needs to be adjusted to work properly. You'll probably have to take out the bolts holding the steering column up.. usually two bolts but maybe four. Let the steering column drop down to gain access to the switch. (MORE)
I'd think 98 MPH in a truck is plenty....but to answer your question, just about every computer controlled car since the late 80s has been governed from the factory. It is in the programming. The reason sited most of the time is safety.....most passenger car tires are only rated around 105 mph. Some… of the high performance cars that were equipped from the factory with Z rated tires have a much higher governed limit. (MORE)
It is a red button usually located in the passenger side footwell on or under the kickpanel. It will be marked to help you find it.
No it wont hurt anything,as long as you wait till it stops rolling to put in in park.. Ive done it a million times..
Disconnect the battery or pull the fuse to the horn then have an auto tech correct the problem.
When engine oil leaks past the turbo seal it can collect in the innercooler. This collected oil then can be sucked into the engine and burns as fuel. This uncontrolled oil that has now being burnt as fuel causes uncontrolled revs of the engine resulting in over rev of the engine. Since the oil is no…t metered by the fuel system, turning the ignition key off has no effect on stopping the engine and the engine will continue to run uncontrolled until the oil source is consumed or the engine fails. The only way to try and stop this over rev on collected oil is to cut off the air to the engine. Cloth towels, shirts or any other cloth like material placed over or into the air intake to shut off all air to the engine can work. (MORE)
It depends on the engine. A diesel engine will stay running until the fuel source is removed. Gasoline engines need the fuel and spark to stay running. If the engine fails to cut off it could be an electrical problem, mechanical problem, or your may have accidently put diesel fuel in your unleaded o…nly vehicle. I would need more details to answer this better. (MORE)
Some cars are designed to do that; and the radio will shut off when you open the driver's side door, the lights will probably "time out" after 30 seconds after leaving the car. if radio is aftermarket the installer gave constant battery power to memory and power leads p.s yellow wire gets constant p…ower for memory the red wire gets hooked to key on or accessory terminal on fuse box (MORE)
Since you did not list the year, make and model, the only way This could happen would be if the ECM detected a problem with the VSC and set the engine and transmission into limp mode and then the problem was so severe it stalled the engine.
