Stalling issue on my 94' Jeep Grand Cherokee

Asked by Jan 17, 2015 at 03:46 PM about the 1994 Jeep Grand Cherokee Laredo 4WD

Question type: Maintenance & Repair

I have a 1994 Jeep Grand Cherokee Laredo
V8 5.2. After about 10-15mins of running
wether I am letting it idle or while driving
the engine cuts off and stalls and it will not
start back up untill i let it sit and cool down.
Some people told me it was a fuel filter
issue, some say it's a PCM issue but most
people are saying to replace the Crankshaft
position sensor(CKP). Well i bought a brand
new CKP sensor and am having my
mechanic put it in for me on Monday due to
the lack of tools at my disposal. I am
hoping that this will solve my problem.
What are the possibilities that the CKP
sensor is the actual cause of the suden
engine cut off?

that sounds like the issue to me does it do it more in damp weather??...very common with that type of CKP .. ...// also check the coil as well the have a multi layer metal heat sink that rust up and expand cracking the coil and when they heat up causes the spark to go to ground

Damp or dry weather. It stalls out. Checked everything on it that can get to. Coils are good, fuel pump n fuel filter are fine.

Well turns out to be the one thing I didn't want it to be. The PCM is bad.
