93 to 94 PCM HARNESS Conversion HELP!
Re: 93 to 94 PCM HARNESS Conversion HELP!
Ok, I disabled VATS, no deal....
I was able to log a sec or two... I'm getting DTC #42 EST Grounded
I'm gonna search for definitions... any thoughts?
Thanks.

change the ign. module. I was getting that code also when I did the swap, but my car still ran fine. I changed that and havn't got a engine light since.

Max93, you said your car ran fine, well mine will start an then die after 2 seconds... I hope it IS the ICM....
I've been doing all the testing I can think of, from checking continuity on all the wires to checking the ground wire. Everything checks out ok. The PCM is known to be good.
It runs good for the 2 secs
until the PCM throws a DTC42, then it cuts out the fuel.

mine would run for a few minutes the the engine light would come on, but would still run fine. I tested every thing also and found nothing wrong. I bought a module for a 94 and all was good.
