95JeepGC

I got a 95 jeep grand cherokee limited 5.2 V8 AWD automatic.
Ok now here's the problem when the engine is cold it starts up fine and the idle is good, put it in gear it's ok. Now as soon as it gets to normal operating temp it stalls even dies out when in gear or in park. I tried the simple tune up still the same. Any suggestions? Thanx

sounds like you may want to check your fuel supply. Often the pumps will work when cold, and quit after they have to pump for a bit. be something to check. the pumps are in the tank.

does it run when restarted? what sort of outside temps are we talking?

Sometimes it runs when restarted and when it does I can have it steady at 2000 rpm then it stalls or hesitates. Outside temp between 88 to 96 degrees maybe a 10% humidity. Also the fuel pump has been changed roughly a year ago.

Because it does run, then dies, to me it really sounds fuel related. I just don't know how much the computer has to do with that. Maybe there is a problem with how its reading how the engine is running and either flooding it out or cutting it off. Things that effect spark normally either work or don't.
do some search on crankshaft sensor and cam sensors, and see if anything sounds familiar. I think there is more issues with those if you have the 6cyl.

keep us posted, and the more info you can add the better.

X 2 on a bad fuel pump.

Well i'll try the process of limitation maybe something will come up. The crankshaft position sensor and cam shaft sensor maybe the issue. With the fuel pump I doubt it cause on my relay it triggers it fine and I could hear it pump pretty strong.
