Most wire shorts have been tracked to the drivers side electrical boot h
housing.You can open door and pull boot back to check.
Chrysler just don't build JEEPS. Dale

Thanks for the information you guys. I'll have to look for that box more carefully. By the way thanks for the pictures. Can I get a used PCM off a 93 at a junk yard and then have it programmed?

Yes that wire harness boot gave me problems before with the back windows not responding. I have to move the door back and forth or wiggle the harness. Man I think Chrysler is rivaling Microsoft now for the crummiest, most inferior product that still makes the most money...

My Jeep has been down for over a month now and my friends won't be friends if I don't get there borrowed car back to them. I have some problems that are inhibiting me from being able to do some kinds of work on the car as well as not having the money to throw at it...

Please keep the ideas coming... and thanks again!

Oh yeah you're right... Chrysler builds CHEEPS not JEEPS....

You don't need to program anything. Unplug the old one, undo maybe 4 or 5 screws holding it to the firewall put the new one in place and bada-bing your back in biz. Usually you just get a replacement based on the part number of the one already in there.

The dealer you talked to is going to want to sell you a $600-$800 oem PCM that's really no different than the one you will get via an auto parts store. You need to find a way to get someone to tell you what PCM part number you have by either looking at the sticker on your PCM or using your VIN at the dealer and then finding out what the number would be if your vehicle didn't have theft. That will be the number of the PCM you'll want to get your hands on. You can check on EBay once you have that number, maybe you'll luck out.

Were you able to get away without programming or having yours programmed??? Without theft I would assume once hooked up there is nothing to interface with any of the old security sensors so it should not be a problem.

I did luck out and won the bid on a remote last night on Ebay. I got it for $26. The guy had emailed me the programming instructions and from what I saw the electric door locks don't have to work. I'm going to try that first since it would be easy and the cheapest and since I already bought it...

I will start looking into the part number on the PCM too...My next questions might be about fixing the wireharness or at least try fixing one of the door switches so it will reset the system. Money is a problem right now so getting another PCM might have to wait anyway.

Thanks!

Yeah the PCM is a total plug and play type replacement. No programming is involved. Disconnect your battery cables and then you take off the big connector. Detach it from the firewall. Hang the new one in place and plug her in. A 15 min no brainer especially if all you're doing is replacing with the same part number. You would be a bit more on the edge looking for a non factory theft PCM for a Jeep with factory theft but I can't see any reason this won't work. A recent post here someone else had the exact opposite problem as you. He had wound up with a PCM that had factory theft in it. It was causing his Jeep to act like yours. He got another PCM without theft and he was back running.

In fact PM me if you need to, he seemed to have a junkyard close by that had these things available and I wonder if the PCM he couldn't use is still there. Otherwise keep your eye on Ebay.

Well I got the remote. At first it would not program and I thought it was due to my electric door lock/unlock that will not lock the doors...only unlock. I kept trying and did finally get it programmed so I can unlock the doors with it. BUT....the $#$#@@ security system is still not reset. I'm assuming it needs to actually have the door do a full lock unlock cycle to reset or the PCM is bad or the security portion of it anyway.

Does anyone have any ideas from this new turn of events??? I'm still considering getting another PCM but want to wait until I have to because of the cost.

I had your exact same problem last summer. I replaced the PCM and it fixed everything. If you're still having issues I'd give this a shot.

valhalla3 · #38 05-07-2006, 11:13 AM

Hey - Thanks for the response! Really you had the same problem? Did the security light come on after the key was left on for maybe half a minute or so? And did your check engine light not come on anymore? I don't know if you saw those thins in my earlier posts. Also did you not have to program the PCM when you got it? Did you get a new one or a used one?

Thanks!

Val

My security light was coming on, so I disabled it by grounding it out. I'll try to find the how to on how to do it. That did not cure the problem though. My CE light would not come on for over 20 mins sometimes. I got a remanufactured PCM through www.rockauto.com. After the core was returned I think it was $140. All you do is take the old one out and plug the new one in. It took about 10 mins and no, you don't need to program anything. I couldn't get the Jeep started for over a month before. After I plugged the new PCM in and reconnected the battery it fired right up. If you decide to give this a try, remember to disconnect the battery first.

valhalla3 · #40 05-07-2006, 06:03 PM

Did you get your PCM with or without theft/security? I just assume get rid of the security system because I can't imagine who would want to steal a Chrysler product anyway...

And if it was stolen I would rejoice and go buy something else....

Thanks!

I got the one with the security / theft. I didn't want to take any chances and went for an exact match.

smithj156 · #42 05-13-2006, 09:33 PM

my jeep did the same shit i put like $700 into and it ended up being the ecu i put all the senors i could think of crank shaft sen cam sen colant sen new coil it just wouldnt do anything the brain is worth a shot after u try other shit like i did but the way i looked at it is i would of payed that or more for a shop to tell me it was the ecu well good luck to

valhalla3 · #43 05-14-2006, 10:21 AM

Thanks for the response.... So did you replace the computer/PCM? Is that what you meant by the ecu? And if you did replace it did that fix everything? Yeah shops are way over priced but not as bad as the legalized crime of the dealership....Thanks!

CanaMark · #45 06-26-2006, 01:14 PM

I got a 1994 and I think I have an alarm issue. My lights just flash, no horn. I just want to rip the damn thing out. And get me a real aftermarket alarm/start. Lots of good info here. So PCM with no alarm, or cps. Is what I will do first.

Thanks
