#79 of 731 1992 Jeep Cherokee Electrical Stall
Jul 22, 2006 (2:24 pm)
I have a 92 Jeep Cherokee with 275K miles that I have owned since it was new. It runs great, but recently it has totally cut off 2 times while driving, the 1st time I was able to restart in neutrall in traffic, the 2nd it would not restart and had to be towed. The dealer had it for a week and got no spark the first day. Day two of tests, it started imediately as if nothing were wrong and they could not get it to stall again. I got it back, drove out to eat, as I was attempting to shift into reverse to leave the parking lot, it stalled dead again. It would not restart in park; I shifted into neutrall after a few minites and it started imediately and drove fine home. Could this be the neutrall safety switch going bad on the transmission?

I have an ’89 Cherokee and I’m experiencing a similar problem. It starts fine and runs fine for about 15-30 minutes then starts “cutting out,” similar to the engine being turn off and then immediately back on. As long as I keep the RPMs up (1 foot on the brake and 1 on the gas), it doesn’t die (but still cuts out). But, if I let the RPMs dip below 1K (stopping at a light), it will die and not restart. I usually have to let it set for about 1 to 2 hours before it will start again. I’ve replaced the rotor, distributor cap, and spark plug wires, then the ignition coil, and finally the fuel pump and still have the same problem. Have you had any luck fixing your Cherokee? If so, how did you fix your problem?

I have the same exact problem with my 97 tsi. I replaced the cap, rotor, crank position sensor, cam position sensor, fuel pump, sparkplug wires, sparkplugs, ignition coil 2 times, air filter, motor mounts and it still giving me the same problem.

Hey, have you found the answer to this problem yet! I have the same issues with my 96'GC, I've replaced the same parts as you. I do get a trouble light from the Crank shaft position sensor. It reads out a intermitant reading of piston 1. I also have violent back fires ever so often. Think I may have to replace my PCM.

I changed the pcm (engine control module). My mechanic advised that he got another jeep into his shop and was advised that the jeep would run if the center connection of his pcm was held up. seems that the connection would loosen up and cause the jeep to idle rough and then shut off. he advised that the circuit board in the pcm may be cracked and changed it. so far it's running great now. you can get a refurbished unit for $250- $300.at your local auto parts store.

It could be any of these problems:
1. emissions system not functioniong properly
2. fault in the fuel or electrical systems
3. faulty secondary ignition system (cracked sparkplug insulator or faulty plug wires)
4. vacuum leak at the throttle body, intake manifold or vacuum hoses.
5. valves sticking.
6. crossed plug wires- check the firing order.
7. valve timing incorrect.

Try changing your crankshaft position sensor first. This senses crankshaft position (tdc) during each engine revolution. The pcm uses this information to to control ignition timing and fuel injection synchronization.

After I changed the PCM, all is well.The funny thing about this is the dealer ship was just as lost! Great information on Edmunds. For all who are out there with a jeep crank shaft sensor or cam sensor Problem. If after changing the sensor and you still have problems you may have to change your PCM;that fixed my problem. I didn't have any luck with having the PCM checked by the dealership. GOOD LUCK!

I have a 94 cherokee sport with this same troubles, and yes I have replaced the crank sensor. Is my PCM in the same place as your 92?
