94 GC No Fire Low Voltage to Pump

[docscomputers]

I see what you mean. Maybe they just do not have any with those numbers available. I looked at the 93,s, 94's and 95's no matching part numbers.

I'll call a chrystler dealer and see what I can find out

I'll be interested to hear what they say about this. I can't make that number come up anywhere. Where did you find the number? Mine was on a sticker on the top of the module. Had to wipe 13 yrs of crud off to read it too. It was printed like this 56029-009.

The differences in that list for 94 as I see it are 7 or 8 different computers. Some of it is Calif emissions or not and some is factory theft or not but beyond that I assume it is minor differences in whatever parts were used building the vehicle.

Are we talking about the PCM on the Drivers Side Inside Fender of the 4.0l GC

You know what, I think someone may have screwed up, I read this after cleaning it up and what they, and I am calling a PCM that they sold me as a PCM has a Label below that says Electronic Brake System. I also notice a *5L* Under a Bar Code at the bottom right side. I wonder even if this is for a 4L engine. Is this the Right Part?

Nope that sounds like the ABS computer. My PCM is on the firewall in the engine compartment passenger side kind of hidden by my radiator overflow tank. Do a search on Ebay for "jeep ecm" You'll see what it looks like.

The jeep is fixed. The problem was the PCM, Had got another from the yard that had antitheft and it would start and shut the jeep down instantly, Exchanged it for 1 without A/T and it fires and runs fine.

Thanks to Dksob81 and Bringselpup they had this diagnosed right off the bat.

To Close and let everyone know that reads this thread the Symptems I had was the jeep would crank and not start, If I waited a few minutes the check engine light would come on and I could hear the pump initiate and it would start and run fine. If it was cold outside you might wait 15 minutes. IT got to the point where it would not start at all. Changed the PCM with a JY model and works fine.

I now have a spare Good Pump and A Extra PCM if anyone needs 1. Pump is tested and will work the PCM is suppose to be a working pull, I can not test it because my jeep will not use it. If interseted e-mail me from the thread.

Thanks
