Ok here is the deal. I started my car up about two weeks ago and it ran fine. I come home after if had sat for the 2.5 weeks and it would not fire.

I pulled the plug off of the coil and there is no spark coming out of it? But i have tested pin going into the coil and it has 12V.
Any suggestions? Any thing else i can test?

Thanks

Ignition Control Module maybe?

 

I hope its that...THe ICM is pretty easy to change.

Can the ICM be tested using a multimeter?

Thanks

???

 

ummm i don't think so...i just bought a new one the other day..they are 59.99 from autozone...if that doesn't work...take it back!

 

Shoebox's test here will tell you what is wrong..

If there is no spark comming from the coil, it could be a bad ICM, or PCM, or opti..Usually the ICM or opti would fail before the PCM...Test the "B" connector at the ICM, and if you dont get between 1-4 volts, its most likely the opti, or the opti harness, or the ICM..good luck..

 

Thanks...i'll try that.

Ok i have now tested on the harness from terminal A to ground and D to ground and have 12v. When i switched the meter over to AC and tested from Terminal B to ground I had pretty much nothing...some mV reading. No where near the 1 to 4V.

I'm now going to test the harness from the opti to the pcm. If that checks out ok i guess that only leaves me with a bad ICM or bad Opti.

Can a advance or auto zone test the ICM?

Thanks
Travis

 

i dunno about that....just buy one and if doesn't fix it take it back...lol

that's what i did!!
