I had the PRECISE problem on a 2001. I looked at every post and every hint or solution provided. Only a few had the problem I had and a poor battery, dirty battery post or battery ground fixed some of them. It didn't help mine. On my Jeep, not only would it run perfectly for a few seconds (I think 15 was the max) it would then totally shut off without a stumble or backfire. ALSO the gauges would sometimes work, sometimes they all remained dead. The problem was a PCM, the programmable control module. On my Jeep it was located externally on the firewall, directly in front of the passenger area. There was a cage over it but you could see it and the three connectors that plug into it. The bolts on the cage were rusted badly, the hinges on the bottom were rusted solid. I had to remove the reservoir bottle in front of it to remove it. I got the VIN number from the vehicle and the mileage (VERY IMPORTANT) and trotted down to AutoZone. They found one in about 20 minutes of looking and had it pre-programmed and shipped to me in 4 days. The old one had a return value of $60 or $70 and the total cost for the new one was $246.00. Many times you buy one of these and then have to go to a Jeep dealer and have it flashed or programmed. They did this one and the cost was dirt cheap when compared to everywhere else. It plugged in and runs perfectly. (over a year ago and 27,000 miles)

does your SKIM light come on first before it stalls?? the sentry key immobilization module.... it shuts your car off afer 2 seconds if the key your using is not the proper one or is damaged.... or if the SKIM module is going bad. mine stalled alot a year ago but it was after it was running for a while like when i came to a stop sign..... that was the PCM or ECM that is mounted on the p/s fire wall in engine compartment...... $189 of ebay

Do you know where the skim is located on the vehicle.

I just installed the skim module on my 2000 GCL and it still shuts off but i noticed the security symbol is blinking before it stalls, which it did not do before, it just stalled. I still have the gauge problem , they are dead.

THAT SKIM MODULE HAS TO BE PROGRAMMED BY THE DEALER TO RECOGNIZE YOUR KEY. OTHERWISE IT WILL SHUT OFF. YOU MAY JUST NEED THE REPROGRMMING NOW.

I have a 1997 jeep grand cherokee limited 5.2 and when i drive it , it will be doing fine then all of a sudden it looses rpms and is guttless. almost like it is getting no fuel. it is throwing a check engine light. but i don't have a way to read the code.
Jan 29, 2011 (11:44 am)
you can get the codes by putting your key in the switch and turn it to the on and off positions three times. DO NOT START IT. on the last turn leave it in the on position and count the flashes of the check engine lite. there will be flashes then a slight pause then more flashes. when it is finished it will flash 5 times then pause then 5 more flashes . 55 is the code that let's you know it has finished it's cycle. after you get the codes you can go to autozones web site and it will tell you what the codes mean. or you can go and have a mechanic test it for you but they will charge you about 80.00 for something you can do free. the chiltons manual is a great investment cause it has all the codes listed in it and will tell you how to do the test i just described. i hope this helps. steve

Lets see if I can add a bit more to this. My daughter has an 03 Grand Cherokee Limited with the 4.7. It stalled on her last night. I went over and it started right up. Smelled real bad of gas after starting. When she got off work, I had my son driver me over so I could drive it home. 2 miles down the road, it dyed like the key was turned off. Started back up and down the road for about another 2 miles when it started to dye and the tach went nuts. Started back up and drove it home. When I got home, my son said it smelled like gas bad every time it stalled.
Brought home the scanner and it had high air flow, Ign Crank Sensor, Knock Sensor, Evap System ( had this for a while), Trans engine Speed Input. I figured some of the codes where from the crank sensor going bad. My son inlaw brought home an aftermarket crank sensor and we put it in. Car starts right up and runs for a couple minutes and dyes. Crank Sensor code again. Maybe bad or the wrong one?? Run down to Chrysler and buy another one. Install and car starts right up. Dyes right away. No codes. Start up and runs for twenty minutes or more while I eat dinner. Keep going back to check and its still running. Go inside to grab my wallet to take it for a ride and it is dead again. WTF!! Try to start it and it just turns over and doesn't fire. Wait a while and go back out. Try to start is and it sounded out of time, rpm gauge is going crazy, and smells real bad of gas. Wait a minute and try again and now it sounds like it is just turning over with no spark and barley any compression!!!!! Jeep has 128k miles on it.

Without being there to check a few things, I am guessing. I know many Jeeps with far more mileage on them without jumping time or breaking a timing chain. BUT that is what it sounds like. That "free spinning, no compression" comment is what sort of rings the bell. To know for sure, pull the valve cover gasket and turn it over. I don't believe the 4.7 is an interference engine. (I don't think the valves kiss the pistons when the timing chain breaks) Check with your dealer to be sure. If not and if the chain is the problem, replace the chain and gears. Be sure to pull the oil pan and empty it and clean it thoroughly. Remember the oil pump and pickup as well. Best of luck...

As of Feb 1 2011, I have changed battery, added ground from head to firewall, cleaned contacts, installed new skim module and had it programmed by dealer and two new keys at the same time, also installed a new ignition switch and it still stalls after 2.5 seconds and the gauges still dont work. Is it time for a new pcm/ecu ?. I am running out of patients with this thing but i love driving it and it looks like new. Any other suggestions.
