If the problem is not fuel related, check your ICM. Also, If it is the 7.3L diesel, you want want to check the ICP sensor. I am not sure if the 94's had that system on it, but it wouldn't hurt to find out. I know on a 96 PSD that I worked on, it cranked over, but it would not catch. We hooked it up to a scantool and read the error codes. Then we found out that the ICP sensor was bad. We replaced it, and then it started. There was a system that the PSD's had that determined how hard to inject fuel based on oil pressure. The ICP sensor is what measures that. Other possible causes:
Bad-Corroded Wire or Bad Connection
Malfuntioning Fuel Pump
Plugged air filter (rare)
Could be a faulty ground wire. Not very rare to happen
You may have a faulty ignition switch. The ignition switch feeds the fuel pump.
This could be a bad ignition switch, ignition relay, or ignition fuse.
The ignition switch could be bad if a Hyundai Elantra has no crank and then starts. The fuses which are tied to the ignition should also be checked.
I had the same problem with a 1992 Park Avenue with the 3800 engine. I first replaced the electronic ignition but that did not fix the problem. I then replaced the crankshaft heat sensor. That fixed my problem.
Ignition is required for an engine to work. Failure of ignition would prevent the engine working.
you did not mention what year, but are you sure it was the ignition and not the anti theft system. If you think it could be the anit theft system, than you can try turning the key on for 10 minutes and than off for on e and repeat this and than see if it starts.
Could be a bad ignition switch....
Your alternator is not working.
When the signal lights are not working on a car, there are a couple of things that could be going on. One could be that the bulb needs to be replaced. The other possibility is that the signal relay needs to be replaced.
it could be the control module
Something is keeping power to the ignition coil. You need a wiring schematic and trace the wiring.
The fuel pump keeps running with the ignition off because it needs to be replaced. ?æThere could possibly be something wrong with the wiring.
Could be a fuse, could be broken wiring, could be a dead battery.
sounds like an ignition coil
Try an ignition switch.
The ac could be causing the problem. Turn the ac off, and watch the compressor clutch to see if it is not engaged. If it is then the compressor or clutch could be bogging the engine down.
Hi, Could be the fuel pump if it just started or the fuse or relay. Steve H.
Check the exhaust ignition interface. It could be a simple problem in the core module defribilator.
There could be a switch that has gone bad in the headlight. The entire assembly will more then likely need to be replaced.
if fan is electric,the radiator thermostate could be wired wrong/faulty.
What could code po300 on chevy 5.7 liter mean
A bad ignition coil can cause your 1987 Acura tachometer to quit working. A bad tachometer cable or ground wire can also cause it to quit working.
It sounds like a bad ignition switch or possibly a fuse. Could also be the sending unit on the injection pump.
most likely a dead ignition module, the accessory part of the ignition goes awry, seen it happen a couple times after you install a new head unit.
