that would be your throtle body sensor which is behind the air filter. there are two sensors placed behind there on the top behind the air filter cover. it wasn't that hard for me to replace the one on my 2000 JGC. mine was having problems starting and staying started here and there then it just wouldnt idle and would cut off if i wasn't driving a certain speed. it was hell jsut to get it to go with out stalling, what is you RPMs saying when you first try to start it before it cuts off?

I am not sure since I am not there doing the starting. It just starts no problem but won't idle. I parked it 3.5 months ago and had the guy at the storage lot start it for me. He said it would go up to around 1000 and then drop off and dye. I am leaving tomorrow to albuquerque to work on it. I will try the throttle body sensor first. If you think of anything else that it might be please let me know as it has been some time since I worked on engines the last one being my 89 grand wagoneer that I rebuilt the 360 in, but this is a totally different thing now with computers and sensors and the such. I am hoping for something simple like what you described otherwise I will have it towed to the dealership on saturday and have to leave it with them until I get back up there next month. Thanks again.

Feb 06, 2009 (8:55 am)
Been looking at some of your posts to see if they mirror my problem but none quite do. Just got off the phone with my neighborhood service station who couldn't figure out what was wrong. Here's the problem:
On cold days (especially) engine stalls and cuts out even after its been running for a good 20-30 minutes. Seems to happen especially when I'm moving slowly (<20 mph) down a side street and go to make a turn. Also happens just sitting in park and sometimes when I go to move out at a traffic light or stop sign. Thought maybe there is a fuel system problem but mechanic said no because it starts right back up. He put it on their diagnostic machine and it's not showing any codes or problems. Asked what to do and he said probably it's an electrical problem and will need to go to the dealership (AHHH!!). I'd appreciate any suggestions or advice. CB

Just ran across your post. Have a question for you. When your Jeep would stall were you applying the brakes at the time?
I'm having a stalling problem and my mechanic can't figure it out. Said basically take it to the dealer or wait for it to get worse!
#442 of 1241 93 Jeep GC starts rough then dies check engine light is on...
Feb 07, 2009 (10:25 pm)
I have a 1993 Jeep Grand Cherokee with a rebuilt engine in it there are about 20,000 miles on the new engine and just turned the car over 249,000 the other day. Last week the water pump and the fuel pressure regulator were replaced and about a month ago i replaced the battery cables (and yes the whole wiring harness battery cables not just the ends). And now after the water pump was replaced the check engine light came on accompanied by a rough start. The engine turns over and over and over and then finally starts up soon to die with a jolt and a shake. It does this a few times until it stays running for a little bit longer then finally after about the fifth time i try to start it the car finally stays running. But it is idling rough and once i put it in drive it dies again. To make a long story short I finally get it running but just today it started to back fire while driving (we all know thats not a good thing) and it's having trouble finding the right gear to get optimum performance. PLEASE somebody tell me what the hell is wrong with this gd stupid POS! I don't want to put in a bunch of money to fix it being that it is only worth $700 I just want it to work and not die on me.
By big red needs some serious medical assistance so please reply if you know whats going on with her.
#443 of 1241 Starts Hard When Warm

I have a 2001 JGC laredo V8 auto, that I just got,here's the problem, It starts great when cold but when it runs for a while and I shut it off and wait about 45min to a hour it starts hard ( Have to crank for around 10 12 seconds is this normal ) have to crank it longer then I did when it was cold sometimes longer then others, I changed the plugs, no distribitor or rotor. I get from reading in the forums it sounds like it might be the Crankshaft Position Sensor? Changed the CPS seems to run smoother but still starts hard when hot What if the battriey is smaller the the orignal? Thanks

#447 of 1241 2000 Grand Cherokee Limited 4x4 4.7V8 Stalls
Feb 22, 2009 (2:44 pm)
I've read most of the posts and nothing quite like this one. My GC stall at highway speeds, 20 miles per hour and even stop. Just stops when it want too. No codes in the system. I've changed the CPS as many people indicated that item was a common problem, new battery, cleaned the grounds, new battery terminals, 3/4 tank of gas. The dealership said I needed a new "brain" before they could trouble shoot it, because for some reason it would erase all codes whenever this problem occurred.
One thing I have not seen mentioned is after mine stalls, you sit for maybe 1 or 2 minutes and each time you try to start it, it will crank, no start, but the fuel gage is reading below zero. The rest of the lights and gages work per normal at that point. Now after awhile when you turn the switch on, the fuel gage registers the 3/4 tank and it will always start right up!
When I first drove yesterday after all the stated repairs, it ran fine for the first 15 miles, then quit about 8 times over the next 6 miles getting home. It alway starts after the fuel gage starts registering and has never failed to start. It is those honking horns at the light that get me..ha.
Some one told me that the GC fuel gage ground was thru the ECU or PCU don't remember which, but I assume they mean the main "Brain".
Even the manual code reading of turning on the switch 3 times only gets "done" code, nothing else.
Also, not sure if this is realated but I get some beeps after the seatbelt warning etc. The last thing is two series of 3 beeps. Very distinctive beeps. Always 3beeps and short pause and 3 more. Ik can't seems to find anything about these beeps.
Anyone have a solution to either of these problems? My next step is replacing the ECU, the local parts place needs the vin, mileage,etc so they can flash it before sending it to me. Anyone had any luck changing the ECU?
Thanks for your assistance.
