#723 of 1069 02 cherokee 4.7 just started stalling now NO START by cyclonetalon

Jul 26, 2010 (8:54 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 1069 starts 3 seconds, no gauges, fuel pressure good by scottj1

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 1069 Moisture in gas line by wilson72

Jul 28, 2010 (11:43 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....

Had some work done recently on a/c. They suggested a new battery due since they had to jump it after doors being left open for a short time. It stalled out me in drive thru a week prior. Now it is doing at stop signs more and more. I just purchased new battery. Got car home and stalled in driveway. The rpms idle up and down. Then eventually it goes out. This is the most it has happened ever in this car. It was due a new battery no doubt. This summer is very hot compared to last year. I have read other posts contributing weather as a factor? I like this car but am stressing now. Any ideas? Thanks!! ---

This is a 4.7 V-8 engine. I should have mentioned that. I apologize.

I have the same stalling issue with my Jeep Grand Cherokee Limited 5.7 Hemi. I love my Jeep and this is my second one, but honestly, I would not buy another one.
 
My jeep starts up fine and drives well but I can tell when the gas isn't getting through to where it needs to for the car to continue to run. My car is shutting off at stop signs, traffic lights, and just about an hour ago while in motion on a very busy road. Normally after attempting to turn the engine a couple times it will start back up but the check engine light will always come on. After I park the car overnight, check engine light is off and I wonder if I'm going to be starting and stopping in the middle of busy intersections the next day. My 5 year old daughter was in the back seat today and cars were just coming up on me (while stalled) really fast in the rear before they saw me and my hazards on. Scared and after maybe 10 attempts to restart the vehicle without success, I gave it a whole lot of gas and turned the key until it started up. My jeep has 60k miles on it and I used mid grade gas. I used to use premium gas but the problem only seemed worse, so I went back to mid grade. The car sputters at time and other times I'm the quickest SUV on the road.
 
My two rear inside door handles snapped off because the handles are mounted to the panel which is only hard plastic (bad design).
 
Two days ago my LCD GPS Screen went out and when it's out I can't control the CD player or the steering wheel radio controls. The screen will come on first thing in the morning, but shortly after, will go out.
 
The driver side of my car leaks when it rains, driver side floor will be flooded but sunroof doesn't leak. Those water things that run from the sunroof down the side of the windshield to allow water to flow obviously were forgotten when the car was built.
 
Although the DVD player still works, my two front door handles are cracked and look as if they can only take a couple more pulls before they snap off as well.
 
Oh I forgot... when the car stalls, occasionally I will smell gas inside the car. Actually, I've smelled the gas inside the car before, and the car had not stalled. The EPS SYSTEM OFF light comes on because the system just shuts itself off when the car acts up.
 
I don't think cold weather has anything to do with the stalling because I just moved from MA to TX. When in MA I never had issues like this but I could tell the problem existed. Since in TX as of July 15th, I think it's time to get a moped for traveling seeing that the weather allows and it's more reliable. One last thing, I have also noticed that sometime when I accelerate the car jerks as if it were going to cut off but the gas got through. It does sound like water is getting in somewhere causing the problem.
 
Chrysler agreed to fix the door handles for $1000 after my car locked on me at the grocery and while my daughter was in the back seat locked in the car. She absolutely would not climbed into the front seat (per mommy's instructions to never climbed into the front) to unlock the door for me and the rear handles were gone.
 
Someone please, if you have any suggestions before I call Chrysler in the morning to give them a piece of my mind, I need information on the stalling, leaking, LCD/GPS screen failure, steering wheel controls and cheaper fix for the door handles.
 
Thanks!

My driver side door handle did the same thing. Unreal! My passenger door side is about to do the same thing too. I am the only passenger so luckily only one side is the problem. We took it out again tonight. It idles at stops signs below 1000 rpms lucky if it gets to 500 rpms. I can tell by sound when it is going to give out and can rev it to go. I don't have any check engine lights or any other indicators. It was due a new battery. The door handles to replace are high. Most people say to call salvage places to try to find a new door handle. I am so bummed. I had an Infinti Q 45 1995 with over 200,000 miles. So far with the a/c problem, exhaust manifold replacement, I spent less money on the Q car than the Jeep. Should have kept it. I had no luck with Chrysler on their crap doors. I wish you luck! I agree the hot weather should not have anything to do with it. Wondering if we should try to trade it in? Drove around to get gas out of car. Added fuel injector cleaner and will fill it up with better gas to see if that happens.
