Question ID: 773520
My car was driving fine when it just flat-out stopped.  I thought it
could be the timing belt due to the mileage of the car, but I popped
off the cap and viewed is fine.

When I put the key in the ignition and turn it over to the ignition
position, the check engine/oil pressure/air bag lights DO NOT light up
like they should.

The car cranks over... But doesn't start.  It seems to me the PCM
and/or main relay coil are suspect.  All fuses appeared good...but I
could have missed one.

I have reason to believe a low oil pressure signal might have been
triggered to shut down the fuel/engine.  I do not know if there is a
switch or procedure I have to go through to restart the system and
clear the fault. (I have not disconnected the battery.)

Any help would be would most likely be the PCM/Main
Relay Coil if a part failed...any method of troubleshooting these for
the real problem would help along with any reset-procedure for the oil
pressure shutdown/PCM shutoff.

I put $5 because if it is a simple fix like "push a button in X
location" that is worth $5.  If you have a more detailed
fix/troubleshooting method, I will increase the money to $15 no

I am cancelling this question out... You were actually part right with
"ignition" but it wasn't the ignition switch... it was just a freaking
15A fuse for the ignition coil.

I think the spark plug wires were old/abused and kept shorting it out.
 I should have cancelled this the next day because I figured it out
then when I checked the fuses.  I don't know how I bypassed the 15A
fuse that was blown... but it kept blowing until I replaced the cables
and now hasn't blown since.

Hopefully someone else can use this was ridiculously simple
and an easy fix once I got my hands dirty.
There is no answer at this time.

Air, fuel, spark, compression; these are what makes an engine go. You
probably can assume it is getting air and that compression is okay, so
check spark and fuel delivery.

Good luck!

I already know this... It isn't getting spark because of the
computer/main relay coil/ some kind of safety switch or computer
shutdown mode.  I think I'm just going to get a scan tool from the
parts store, but I don't know if it can tell me the PCM is bad or not.
 There probably will be no "error codes" because the check engine
light is not lit, nor is the air bag, oil pressure light, etc.  It is
in the electrical system in the ignition system.

Thanks anyway.  I just wanted to avoid having to buy a PCM or have it
towed to a shop for them to tell me the PCM is bad when I can fix it
myself but I just don't have the dianostic tools to run on the car...
stupid electronics.

I had another car do this to me (would crank but not start) and I
think it was something in the ignition system with the faulty built-in
alarm the car had on it.

The fact that certain lights don't come on when you turn the ignition
on is the "key" statement.  The oil pressure light especially is a
very simple circuit which has nothing to do with the computer.

It sounds like for some reason you aren't getting power to the
ignition circuit from the ignition switch. You know the ignition
switch is getting power because it turns the engine over.  You
probably have a bad ignition switch.

The switch has multiple contacts in it, and part of them can work
without the other portions working.

I have a few more troubleshooting tips on my website:
