Hi, my jeep liberty didn't warm nearly enough before I drove it last evening (I know, I usually let it warm up, was in a hurry). I'm from MN, it was -1°. I was driving slower until the engine could warm up. On my way home (about 3-4 miles down the road) the low oil pressure light came on. I...

Hi Jeep Forum, I drive a 2000 Cherokee Sport 4WD 6 cylinder 4.0L. I took it to the mechanic the other day to get a check engine light problem addressed and asked them to pull the error code as I couldn't remember what it was. They couldn't get a reading, and said my PCM was bad. The shop...

I was given a YJ with an intermittent gremlin that kills the engine at the worst possible times (up a hill, around a curve or middle of an intersection). I am on the verge of getting a new intake and a carburetor and simplify this issue (mostly sarcasm, but will have to do something). I am a...

Hi, I'm a new member. Apologize in advance if this is in the wrong section. I have 04 and 08 Jeep Grand Cherokees. I'm having an intermittent starting issue on the 2008. Sometimes when the (plastic) key is inserted into the ignition, and turned to start, there is no starter solenoid click...

Good evening fellow Grand Cherokee enthusiasts. I'm hoping someone here can give me a hand with my issue. I have replaced the engine on my '06 3.7L G.C. a couple of weekends ago and seem to have inadvertently pinched a wire or something similar. I was driving home from work this evening when the...

First post here, so I have a Cherokee that the harness and renix in CPU are bad does anyone have a site that sells either or both of these? I couldn't find the right harness on painless. Thanks in advance (and yes I have searched but I'm new to wiring)

I have a '96 Laredo, still trying to fix the hazards, turn signals, dome light, and power seats/ windows to work-- so far we've found a way to bypass a Green/w Black Stripe wire to make the dome lights, and seat work, but now, the Jeep wont even start! I was thinking it was a security issue...

I have a 2000 JGC loredo v6 4WD. I my car stopped shifting so I pulled the fuse on the TCM and everything works, except overdrive, as long as I shift manually. Im ready to fix the problem but i cant find the TCM. Is the TCM integrated in to the PCM? If it is integrated into the PCM how does...

Was looking at a 2006 KJ at a dealer today. Gas gauge read half, but the overhead console display said 14 miles to empty. Not sure what was actually on the tank, but what could make them give such disparate information? Also noticed on the CarFax repeated test of the electrical charging system...

Alright so I'm at college right now and I don't really have a whole lot of time/money to invest in this thing, but I would really like to get my zj running again without taking it to the shop. What's wrong: - No reaction from gauges after switching the key to the on position (i.e. no reading on...

I've played 4 brands of hell trying to find the right engine module, let alone someone who has the part as a new/reman, and not a used part, as that's just putting a timebomb with a dodgy timer back into the mix. So without further ado, here's the list, by transmission type, then by year. RFI...

I'm having a injector 5 code so changed it to no avail. Then traced and tested all injector wires to the PCM and they all came back good while not running. I've decided to try replacing the PCM but the dealer wants my arm and leg so salvage or reman it is. Does anyone know how to flash the...

Hey guys, I just bought a 2001 jeep xj.100'000 miles runs great but won't pass emissions testing. It keeps giving a not ready signal to the emissions testers and it seems to autozones computers as well.. Changed the computer and same result.. Any suggestions?

My transmission is acting up and I have no clue where to start diagnosing the problem b/c I'm a girl!! LOL Anyone have Ideas? I reset the computer (learned here on Jeep Forum) and it fixed the problem but then it comes back.. The problem is that it won't go past 2rpm and won't...

I've had a '93 Grand Cherokee Limited for since about October for my first car. About a month ago I got in and thought I heard something fall in the back after I started it, so i turned on the back seat light to check it out. After seeing it was nothing I realized the light had gotten stuck and...

I'm being told that I need a new PCM. :thumbdown: Dealership wants 800 or so for the re-man one from mopar. Does anyone have any experience with rebuilt or re-man PCM's? Any good places to buy or should I just pony up on the Mopar? 2007 WK CRD

Massive Engine Problem :( Hi Everyone, the Harness from my computer melted on my exhaust manifold. I cut out the bad wires and soldered in new ones. The Jeeps starts and then promptly dies. It sounds like its only running on 4-5, not 6. A few seconds after it dies, it kicks... no idea...

I am looking for this part. Any ideas where I could find one? So far no one has been able to find a replacement. I recently had it rebuilt, but This time it is in disrepair.

My jeep ran fine until i parked it in the garage....When i tried to start it back up the fuel pump would not stop pumping, there was no spark, and no electric going to the injectors. There is gas in the tank, a new fuel pump assembly and new injectors and nothing is working. I thought it may be...
