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 ground
Bad-Corroded Wire or Bad Connection
ECM Malfunction
Malfuntioning Fuel Pump
Plugged air filter (rare)
You may have a faulty ignition switch. The ignition switch feeds the fuel pump.
Could be a faulty ground wire. Not very rare to happen
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.
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.
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.
This could be a bad ignition switch, ignition relay, or ignition fuse.
Ignition is required for an engine to work. Failure of ignition would prevent the engine working.
Could be a bad ignition switch....
Your alternator is not working.
it could be the control module
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.
Something is keeping power to the ignition coil. You need a wiring schematic and trace the wiring.
