they sell pre-programed pcm's for jeeps on ebay for between 150.00 and 200.00 hope this helps because i just paid Chrysler $1200.00( i wish i knew about the ones on Ebay) for the replacement of my pcm and its only been a month and i'm back to the same stalling and i get the key symbol. I 'll be taking my jeep back this week and hopefully they can get to the bottom of this.

thanks for your comment since i posted my comment i replaced the pcm and yes I still have the problem. It still looses spark at times. Everything has been replaced. So if you get anything new please let me know. I have thrown alot of money away and nothing has fixed it.

Looks like alot of us are having the same issue, anything from not starting all the way up to stalling while towing a boat 15 mins down the high way. This is absolutely absurd!!! I have changed everything in my car and I still can't get it started, maybee the goverment should have let Chrysler fall right on it's face, just like chrysler is letting their customers do. I dont think it's any of the sensor's, pumps, hose, fuse or switches ; I think it is the whole wiring harnes it self! It has to be, we replace every sensor, switch, hose, fuse, and the pcm! If we replaced everything its got to be what connects of of them together. Jeep is known for, not have a great electrical system to begin with. I dont know I am not a mechanic, but I do have a brain. Oh were was that brain of mine when I started this crap!! LOL any ways. I spent way to much money on this, At this point is would be foolish to give up. Any one know were I can get a new wiring harnes, that hopefully dose not coast an arm and a leg, i only have a few fingers left.

I am at the same point as you. I was told it could be a intermittent injector problem. One that is shorting out which in turns operates the coil. I haven't done anything with it yet I have replaced everything on my jeep as well. It has cost a ton of money and nothing has fixed the problem. If you find out it is the wiring harnes will you let me know? I have no idea where to get one except from the dealer which will cost alot. If you get a used one you could get the same problem...

That does sound like you have a shorted wire sonewhere. Finding it will be the problem. Mine will run good for days and then will mess up out of the blue. You never know when it is going to happen. Someday hopefully we will find the problem

Yea I went to the dealership looking for a harness and it's basically a billion dollars, but I did find out that their are a few recall's one being with a certain pcm witch I happen to have so i dropped off my car and they are working on it i should hear back in a few days, oh by the way the pcm # is 56043172, the recall is for a erratic idle and intermitan loss of some light's gauges etc.... the pcm needs to be reconfiged not replaced, if you replace it you will still have the same problem, so they say..... till next time, hopes this helps and will let you now how i make out.

#17 of 38 Code#Po300 ? Ramden multiple missfire. 2000 Gran. Cherokee
Aug 26, 2009 (6:37 pm)
I have a 2000 Grand Cherokee Lorado, 4x4 4.7 L My Jeep has been giving me a Code Falt (Engine Light) # P0300 Random Missfire Didplug's. N.G. I Changed all the coil packs. N.G. I cleaned every plug in connecter under the hood with contact cleaner. N.G. I did a fuel rail test lbs. where good. All inj. where good. N.G. I Checked for vaccum, No leak's. Still N.G. Changed Temp. sensor. N.G. Jeep said there was a service bulliten came out, 1 down-load for driveability issuses, And 1 down-load for Tranny. Had them done. N.G. Then changed Cam Sensor & Crank Sensor. N.G. Don't forget every-Time I do one of these repair's, I clear the codes-engine light. And every time that DAMN P0300 Code Kept coming back.Any where between 2-3 days to a Month. Also since this problem My GAS MILEAGE HAS GONE TO ++++ in a hand basket. Know since I did the Cam & Crank Sensor there have been no codes for 1 Month. WAIT till Today A New Code... #P0601 (Check Sam Error) Witch means PCM Jeep want's $700.00 Reman can't get New. So I call around, Turns out NAPA has them 1 Yr. warranty. $121.90. Now it has to be Reflashed. I take it to Jeep they fash it, you know put some brains in it. Install it they road test it, All is well. Another $176.00 for Reflash. I Leave the Dealer Ship drive down the road to the Sunoco Station. Fill Her Up. Get in Start it up. I jot down the mileage so I can check th MPG out. And The Jeep Stalls !!!! I Turn it Over Nothing. No Spark you can here it, Just spining over like a TOP. Im madder then a Hound Dog with Flees. So here I am 40 miles from home 5:15 PM Jeep is Closed. I have no tool's. A Leather Man on my belt. I pop the hood, Take out the 2 10mm scews holding the rad. over flow tank. Pull it out unplug the 3 connecters on the PCM,Take my old PCM out of the box on the front seat. I fit down by the connecters and plug it in, It fires right up. The remann pcm is N.G. Mow I call Napa before they close at 6:00 They said sorry I'll order another. Have it in 2 days. I say wait a minuite, What about the $176.00 I just paid for the Reflash. They said they'll take to the company about it. So I pick a pizza some Coors Light.& go home. With the Idiot Light On Still. 1 YEAR LATER> Today is Wens. 26th let ya"ll know how I make out. I am hoping to change out the PCM & be DOWN. Or am I DREAMING. If I didn't lov this Dam jeep so much, I bought it 3 years ago fro the org. owner with 76,000 miles like mint new. The man littery only sat in the driverside, No Pass. No people, Never used the rear seat or cargo area. For 2 years it was great, But Chasing this problem is driving me nuts.
