#1021 of 1069 94 Jeep Grand Cherokee Stall & won't start by pjd1280

Aug 05, 2012 (9:47 pm)

I can be driving and not only does it stall but it loses ALL power! Also once I get somewhere and shut it off most of the time it won't start again untill it cools off. I have changed the plugs, and the coil, checked the water and the trans oil. This started about 6 mos aga and is getting worse! Help this to lady that service tech poor to fix it please?

I have dealt with same problems with my 97 cherokee. replaced everything with no luck. Did the screw thing, and every other thing that was suggested. I finally stumbled across this video on youtube. I did just what the guy said and that was the end of the stalling/not starting problems. Just thought I would drop it on you. The video is labeled as - 96 Grand Cherokee PCM Repair. good luck PS - if you don't see any breaks in the solder (as I didn't either) go ahead and do like he shows. They can be too small to see.

I have experience with the 6cyl. There is a testing valve on the fuel rail nearby throttle body. I think the 4.7 has a similar one.
You can easily test the fuel pressure - after unscrewing the cap you press the center of the valve by fingernail or tool. If fuel sprinks, there is pressure and the pump is O.K. You can also connect a pressure tester to check the pressure more exactly. If no fuel is sprinking (or very weakly), the pump is not O.K., even if you can hear a pumping sound.

#1024 of 1069 1999 GC Laredo 4.0l stalling by as350b3e

My Jeep has 230,000 km on it. Bought it 2 months ago.
Sometimes when I come to a complete stop (usually right after I start the car), the trottle is not responding and the engine sounds like there is no ignition. Sometimes just giving veeery little throttle gets the car going. Once the car is running again there is no problem anymore. When it does stall, putting the transmission in N, the engine will respond normal to throttle input and putting the transmission in D while the RPM is little higher than idle (600RPM) the stalling goes away. The engine has never died nor does it happen when the car is coasting.
I read somewher that it could be the Flywheel sensor.
Just yesterday I had all spark plugs changed, no change.
Any thoughts?

I built the steel bar tightener today and tried it out as my 97 GC has been stalling the last week. Didn't seem to help as the car wouldn't start at all after putting it in. I didn't shorten the screws, but may try that tomorrow. It just seems the only common denominator among all these "fixes" is wiggling wires just right and being lucky.
 
In any case, this is pretty ridiculous that this is so common an issue without a word from Chrysler. I'm amazed that no one has died yet as their Jeep stalls out in the middle of the highway or going up some muddy hill.
 
I'll share whatever miracle fix I manage to come up with, if that ever happens.

if it is stalling at random it is your computer,,,, i got a rebuilt one off ebay and gave them my year make and model, vin nbbr and mileage. like $200 . installed it in about 35 min..... and it worked great for about 2 years..... then i went thru 5 (yes ... 5) more at the dealer ($1600 for computer , skim and instrument cluster)because of my skim light coming on and you cannot get new computers (ecu) only rebuilt..... but they did not charge me for the other 4 except for the tow charge in... that is when i sold it.... loved the jeep but need something i could depend on
 
good luck
