<quoted text>Well, I just read every post since the get go as I decided to once more attempt to fix the problem,(sound familiar). Like everyone else we need no description of the symptoms. About a year ago when it the stalling issue first appeared I did the voodo torgue screw fix of backing the torque screws a half of turn out and for some strange reason or coincedence I was stall free for a year. This may lend some credibility to the pcm swap. I bought a crank sensor as this appeared to be the main consensus and changed it only experience a non starting cherokee immediately after changing the part. It started fine about an hour later when I went back and tried again, same as before intermittent operation and holding your breath going up bridges in traffic where there is no shoulder to see refuge. I went through the wire harness inspecting for frayed or suspicious bad spots, wiggling a fuse for ignition seemed to help but it was a coincadentaly fix. I am going to pull the pcm and clean it and the idle air valve, try that and buy rebuilt pcm next I guess. Will post results, amazing there does not appear to be a definitive fix floating out on the net somewhere.

Hi, My 2000 JGC Laredo 143K miles started stalling about a month ago. Usually within the first half hour of diving. The engine would shut off completely while everything else stayed on. Took it to the dealership and they couldn't get any readings so they fixed what they "thought" was the problem - they replaced the PCM, cleaned off my corroded batter, and did a complete fuel system service - and $1,700 later - problem still wasn't fixed. So, earlier today they said it was the crank shaft sensor. I'm told that has fixed the problem, though I'll beleive it when I see it. So, if this doesn't fixe the problem, I will probably just give up and bite the bullet for a new car. Which is so disappointing since I was certain I could drive her to 200K miles. But with you kids in the car, its just not worth the wory of never knowing when the car will die.

2000 jeep grand cherokee laredo 4.7L Im getting alot of the problems as the above have described, but my symptoms are intermittant (spell check). So i replaced the crankshaft position sensor which wasnt to difficult 1 bolt,1 electrical connector. But, after a few hours later the symptoms have returned, It hasnt stalled yet but, I'm getting a weird idle like before it'll jump down to 500 rpm jump up to 1500 rpms then back down to 500 rpms, and as i throttle it (while driving) it'll chug 30 or 40 mph then it'll pass it then chug again at 50 or so mph and like I said it wont do this all the time its intermitant. I really thought it could be the crank shaft position sensor, Please help me.

Not alot of people post there results so here we go, from what I've gathered if your having stalling problems accompanied by starting problems that lead into fluxuating idling problems then you are in the same boat I was, I replaced the camshaft position sensor which the location varies depending on what engine you have mine is a 4.7L and it was located just behind the water pump on the left side if your facing the grill. I still had some idling problems and throttle issues so i replaced the crankshaft position sensor, again location varies depending on what you have, mine was located just above the starter motor i put the jeep on ramps removed the starter and the sensor was right there didnt even need a extension. the two bolts on the starter are 15mm and the 1 bolt on the crankshaft position sensor was a 13mm or a 14mm i cant remember but that is good to know before you crawl underneith also right or wrong i didnt remove the electrical connectors on the starter cause there isnt alot of room underneith there so it was easyier for me just to let it hang there. anyways staped the new one in there but everything back together now she runs like a champ. thank you www and haynes couldnt have done it without you!

I have a 2001 Jeep Grand Cherokee Laredo and I had the same stalling problem and took it to get fixed. They told me it was the CPS but replaced that and then another code came up. They replaced 3 parts and kept getting more codes. We have now been told that they could not fix it and that we needed to take it somewhere else. The other day it would not start up after being parked for 10 mins. Any clue that could help. I don't have a lot of money to keep taking it to auto shops.

My wife's 2000 GCL has been stalling for about 2 weeks now. No indicators lights or codes, it just shuts off and won't restart. She has to let it sit for about an hour with the hood up, and then it will restart. Replaced the Crank Position Sensor, which fixed the problem for all of 1 day. The Haynes manual mentioned that you should be able to turn the ignition (without starting) On-Off-On-Off and On one more time, and either an error code or the word "done" should appear on the odometer. Most of the time, nothing shows up, not even the "done." Occasionally, the "done" shows up, but never an error code. It's almost like the PCM can't figure itself out. So I'm thinking the PCM module is going bad. I've got one on order, and I'll poist again when it shows up and gets installed.

Argh,
Well im having troubles again, My Jeep grand cherokee laredo, 4.0L 6 cylinder got grumpy one day out of the blue after me fixing a bunch of other problems.
Right now it runs rough... then stalls out on me while at idle. Then i try to drive it down the road and its stalls and runs really rough. Occasionally i hear a 'POP" sound every now and then come from under the hood, and then after it platters again and continues being a rough car.
NOW... i have recently changed the CAM shaft and CRANK shaft sensors about 5 months ago so i wouldnt think it could be that again! I have JUST replaced the PCM, i replaced the Map sensor, Throttle position sensor and then Idle air control sensor. I have forgotten the other half of the mess i have changed but it's been allot!
Does anyone know of anything else i can try....? or anyone had the same issues? Could it be the CrankShaft sensor again...? but i changed that 5 months ago because the car was stalling out bad like described in other posts. Not as bad right now and only stalling after running really rough and while sitting at idle every now and then.
Please help.

I have a 2000 Grand Cherokee Limited 4X4. I have had it for 5 years. Repair after repair. It stalled on me and would restart 5 or 10 minutes later turned out to be the PCM module at $950.00 for the part. Replace it 3 times. The last time it only had 19,000 miles on it. Called Chrysler to complain they wouldn't listen to my complaint instead asked about the warranty on the car. Very disappointed in the car and Chrysler. Going to sell and never buy another Jeep. PS Shame on you Chrysler!

Fixed... after all that stuff i replaced... it turned out to be the Ignition coil pack. Only $100 from an auto shop and only 10 mins to change it out. The codes it was giving me was P0300 P0301 and P0306 so meaning that theres a missfire on multiple cylinders and miss firing on cylinder one and six... anyways problem fixed..

I have a 2000 Jeep Grand Cherokee Limited (V8). The following similar intermitent problem has occurred a few times within the past year. While driving, with no advance warning, it stalls (all gauges dead), making me control my gear shift, accelerator and brake pedals simultaneously so as not to stall on the road. Some other times when I go to turn on the car and turn the ignition key, the gauge needles whip violently around then back to their starting point, and no response from any system in the car. After an about 15-20 min the car starts again but must work the pedals and gear shift simultaneously to avoid stalling.
Funny thing is that i live where you live and im having the same issue to a T. ive heard from multiple sources that it is the PCM, however, I tend to think its a short somewhere. It can be so many different issues, i would honestly just go down the list on this site and check all these different things. That's your best bet. Most places will say its the battery, but after putting in 3 different batteries, I can honestly say that that is not the problem. best of luck and let me know if you figure out what it is.

I have a stall start problem that is random. running slow of fast the engine will die sometims it will restart in a few minutes , 2 times it took till the next day. no codes show up sometimes it will turn over but not crank. i replaced the sensor that is located under the passenger head light/under front of battery 2 years ago and fixed the problem noone at autozone or oreillys can even tell me what that sensor is or that it even exists in the book for the jeep. does anyone know whay the sonsor is or a solution for the problem. it has a new fuel filter, new battery,when running the fuel pump checks out. when not cranking no juice to fuel pump.

I've been having the same stalling problems with my 2001 JGC 4.0L 4WD. It will stall on the freeway, at a stoplight, seemingly wherever. Though, ever time it has restarted, sometimes taking 5 minutes to finally restart. One time, while it wasn't starting, I turned the ignition to the "on" position 3x and held there on the 3rd time until the code P0320 appeared. I googled the P0330 code and found this forum. Today I had the crankshaft sensor replaced and I'll update shortly if the problem was been solved. Otherwise next I will try backing out the PCM screws, or replacing them with shorter ones.

Tell me when this thread is updated:
