Car Turns Over - No Ignition

[CNorell145]

Alright guys, new problem on the 2000 GTP. The car turns over, the fuel pump whines when you turn the key, but the car will not start up - there is no combustion.

I checked all the fuses, and they are fine. Spark cables are all plugged in correctly, so I'm at a loss.

Any ideas?

Try using the gas pedal at all to get it to start?

Unplugged the MAF yet and do the same thing to try and make it run??

You could bend the tab on the fuel pump relay too to get the pump in high mode, low speed might be out if the resistor is bad.

[CNorell145]

Yeah, I tried giving it gas, no change.

I haven't tried unplugging the MAF yet - I'll try that in the morning.

What tab do you bend exactly for that?

Even though the pump primes, it may still be the fuel pump that let go. How recent before this did the car run? Still cranks at normal speed?

I have had fuel pumps let go in several GTPs I've owned. Mileage varied. Let us know and we'll go from there!

[CNorell145]

It sat for about 1.5-2 months, then I replaced the engine and it seemed to run as good as could be expected (still had large RPM surges at idle, trying to die, as explain in my other posts, which I still cannot figure out).

Is there a way I can test the fuel pump without swapping it? Could the fuel pump potentially be causing the dying issues?

There are about 115k miles on the pump as far as I know.

[CNorell145]

Alright, status update.

Unplugged the MAF, nothing.

Swapped the ignition coils, nothing.

Bent tab 85, nothing.

Thoughts on the new info?

Check for spark at the plugs. Have a spark plug sitting away from the engine plugged in and have someone turn the engine over. Make sure the plug isn't touching metal.

Also wouldn't hurt the maybe pull the injector fuses when you do this.

Also, check to make sure the ICM is plugged in properly. I thought mine was screwed into place but it wasn't. Wiggle it and see if you can push it in farther

[CNorell145]

Tried pulling a plug, no spark that I could see.

I also pulled the fuel rail, fuel is being delivered.

I'll check the ICM now. Is that the long plug that connects to the coils?

[tomtom123]

This

[CNorell145]

Checked it, it's in all the way.

[CNorell145]

I also tried swapping every fuse I could find.

[tomtom123]

Is the ground for the ICM in the correct place?

[CNorell145]

Probably not, I have it attached to the fuel rail... Where should it be?

[CNorell145]

My DIC is also all of a sudden reading 48 MPG if that means anything. Haha

[tomtom123]

Lol that's the problem undoubtably.
Lemme check for a pic. I should have one

[tomtom123]

Crap.. I took the pics on my old phone which is at home. I won't be home for a couple hours. It goes on a bolt near the tensioner like under/behind the ICM/Coil packs

[CNorell145]

What's strange is that it started before attached to the fuel rail, and now it won't start... I'll try to ground it somewhere else and see if that does anything.

[tomtom123]

Thats weird. Might be something else then. I know of people having priblems in the past with their cars not starting right and the problem was where the ICM was grounded.
If you move it and it starts, that was the problem. I recommend putting it where it belongs thiugh =P

[CNorell145]

The problem almost has to be with the spark, right? I just don't know what else to try.
