2000 grand cherokee stalls

I have a 2000 jeep grand cherokee that stalls after 30 minutes or 5 min of driving. There are no codes and it starts right up. A couple of times i had to wait 2 min before it would restart..also checked fuel pressure ok.
Any help would be appreciated.

Try replacing the idle air control motor or IAC for short. i actually had one at work today with your same complaint. and sure enough the valve was a carboned up and wouldnt work properly. and its nearly impossible to clean to the point where it will work properly. cost for the part at a dealer is about $115.

2000 jeep grand Cherokee stalls while drive or idling no codes


which engine? 2000 GC, is a body, stalling is and engine issues.

there are 5 reasons (physics) to stall, and 50 ways. (reality,say head valve stick hot only??? and lots more.)

ill not list them (searching shows my posts doings so 100 times)
but will ask you one questions.
can you save the stall with a fast right foot.??????????
ok 2 .
does the dash lamps (any ) go dead at stall point.?

the scan tool only works best , scanning and driving and for sure
at the stall point, so?
for example misfire codes clear in 1 second if gone.
so you missed that...... real time scanning is best, others like trips
to autozoned are near useless. IMO. why work, blind, ?

for better answers join a real jeep forum (google that)
this forum fxxxa , sux at this, it has NO structure here, nor abilities
to see your car, your engine, and others with issues related.

My 1994 Jeep grand cherokee starts n idles but then dies.


Engine stall or RPM fluctuates at idle.

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

I have a 2000 jeep grand cherokee witha misfiring problem on all cylinders, thats the codes it is throwing. we have replaced plugs,coil,and camshaft sensor.still having same problem. it bumps bad like it...


Hi, think i might can help you, have you done a fuel pressure test if not here what you need to do.

1. Start and run the engine. Verify normal fuel system pressure of 339

kPa +/- 34 kPa (49.2 psi +/- 5 psi).

2. Stop the engine. Verify that the fuel system pressure does not fall below

207 kPa (30 psi) in less than five (5) minutes.

3. If the fuel pressure does not fall below 207 kPa (30 psi) in less than five (5)

minutes, then the long crank time may not be due to the fuel system. Further

diagnosis must be made to the entire engine system.

Hope this helps you, because lack of fuel can cause a missfire and by what you said this is were i would start before spending any more money. If i can help just re post.

Thanks dodge tec

it's in your auto start system. mine does the same thing. after it sets fot 5 mins. it starts. if it is a factory installed auto-start, have dealer check. if it was installed by someone else, theirs a problem with installation or wired wrong.

Stalls out just after starting or does not want to start


your problem is the crankshaft positioning sensor(CPS) located at the transmission bell house.had the same problem with my 99 jeep sport.the dealer said it was the pcm.but when i replaced the cps never had the recurring problem of engine stalling after 30 mins of driving.

1999 Jeep cherokee will start i can drive for about 20 min


Replace, or have the fuel filter replaced. Replace the air filter as well. If it still does it, have the fusable link(s) checked, as if the connection(s) is not secure, it will cause the vehicle to start sometimes, or die while driving. Also have a diagnostics done at your local mechanic, or a local automotive store (usually a free service; stores may vary)
