#719 of 1240 2000 Jeep Grand Cherokee Stalling
Jul 20, 2010 (4:01 pm)
I might have the same problem. 2000 Jeep Grand Cherokee 4.7L V8- When I run the car for an extended amount of time in traffic, stop and go driving or with the ac on in park it will just stall out. I will try to get it started again but the gas gauge reads empty and the check gauges light comes on.
I have a CarMD check engine code reader for my jeep but it always passes with a green light even though the check gauges and check engine lights are both on and the sentry key light is on as well.
While I run the car, before it stalls out, the CarMD reader shows a yellow light but no codes. I've replaced the CPS, fuel filter/control unit, thermostat, fuel injector, put a new AirAid air intake, new spark plugs but still this problem persists. One thing i will say is that the sentry key logo tends to stay on after it stalls but thats just strange. Again, my diagnostic kit, CarMD, doesn't read any codes (Green light with 0 problems) after the stall. I'm at my wits end, I might try to replace the PCM before taking it to the dealership. Any Ideas as to the problem would be greatly appreciated. Why no codes eh?

I am having the same problem with my 2007 jeep grand cherokee aswell. Got the factory remote start and the 4.7L engine. Did you figure out what was causing this? Mine is barely starting and when it does, it just sputters and sounds rough. But will eventually start when I give it gas.
#722 of 1240 will not idle
Jul 26, 2010 (5:59 am)
I have a jeep grand cherokee 4.0 straight six that has suddenly stopped idling. You can start the car but once you lay off the gas pedal the revs will drop to nothing and the car will die.
Any suggestions as to possible faults/cures.
#723 of 1240 02 cherokee 4.7 just started stalling now NO START
Jul 26, 2010 (7:54 am)
I have a 2002 Jeep Grand Cherokee with a 4.7L v8 110,000 miles
Yesterday after about a 20 minute ride on my way home my car stalled and threw a check engine light. I started it right back up and every time I slowed down or came to a stop it would stall but start right back up. I tried making it to the garage to get the code read but the were actually locking the doors when I pulled in.
So I take my car home and I figure I will try to take it to work today and see what happens it did not stall or act up for about 15 minutes and then it stalled and would not start at all. I let it cool down for 2 hours and tried it again but no start.
The engine cranks and the guages are not going haywire, I have a full tank of gas, a decent battery. Another odd thing is my airbag light came on about a week ago for no apparent reason? have not thought much about it.
from my readings i am guessing Crankshaft position sensor (probable) or ECU (possible)
any help would be much appreciated.

Turns out it was the Throttle Possitioning Sensor. Thanks for the input from everyone.
#725 of 1240 starts 3 seconds, no gauges, fuel pressure good
Jul 27, 2010 (5:46 am)
I have read 700 pages of start / stall problems on JGC. Mine is similar to 5, all without solutions that work on my car. I have a 2001 GC 6 cylinder. It drove fine until it wouldn't start and keep running. It starts immediately, no problem. It runs for about 2 to 3 seconds, sounds fine. It will idle during this time, or rev if I depress the throttle. It then stops without any backfire, stutter, or hesitation. It stops, period. The fuel pressure on the fuel rail is normal at all times. The tach, fuel level, oil pressure gauges all show zero during this start / stop process. They never budge in spite of the tank being full, oil being pumped, and the engine doing between 800 rpm's and 2000 when I rev it. Under duress from my best friend, I replaced the cam sensor at the old distributor location. It did not work, nor did I expect it to. I would DEARLY appreciate any specific suggestions that don't include replacing things without being able to test and verify their failure. I was a mechanic for 17 years and I don't blindly replace parts (ok, I did swap the cam sensor but I did this for friendship). Please help... any similar problems with solutions that work are sincerely appreciated.

i would check out the ignition switch as you have no gages when this happens sounds as if have dirty contacts
#727 of 1240 Moisture in gas line
Jul 28, 2010 (10:43 am)
How can I fix this. My 2005 Jeep Grand Cherokee Laredo 4x4 3.7L 6 Cyl. 71,000 mi. The engine light is on and the car isn't running on all cyl. I had a computer reading and it said that there is moisture in the line. I switch from mid grade to hi test gas and I'm adding "Heat", a moisture remover to the gas when I fill up, but after 4 tanks of gas, the engine light is still on and the problem is still there.

if you have that much i the lines i might consider changing the fuel filter(s).... on my waverunner the water gets trapped in the filter and keeps getting in the line....i hva to change out the filter or at least take it off and get all the fluid out and then let it refill with good gas... but that is just a guess....
