out of curiosity when it stalls out what are your fuel trims. sounds like something is cutting fuel off.
im sorry my system crashed and has just gotten back up. you will need a scanner to look at the data and look at the long and short term fuel trims.
Hi, my name is***** can help you with this, does the check engine light come on, for about 2 seconds when the key is first turned on?
Yes, but does the light come on when you turn the key on, for a bulb check?
If the light comes on, then you have all powers and grounds to the PCM, and you have a bad PCM, if all the wires have been ohmed out, then it can only be a bad PCM, A-1 cordones have more problems than there woth, have all the PCM been A-1 cordones?
I would try a dealer PCM, we have nothing but problems with aftermarket PCM's on these,Tim
hi i'm bill let me see if I can help one of the moderators messaged me to try and assist you, I have been with jeep since 1992 and still work at a Chrysler dealer
can you send me the vin so I can pull some wiring diagrams, also we have had many issues with crank position sensors shorting and crashing the pcm if you unplug the crank sensor can you communicate with the pcm, the crank sensor connector is behind or VERY near the distributor you will find 2 connectors there 1 will go to the distributor pick up (cam sensor) and the other will go towards the right that's the crank sensor
Hi Martin, My name is***** the crank sensor tests okay and the distributor and coil is okay verify the timing is still in specs and the engine has not jumped time. Click here for some schematics as well to assist in testing the circuits.
it's rare to see a old school v8 to jump time, you MAY be able to pull codes with the old key cycle method used on pre 96 vehicles do you have all data r the like? if so there is a test for the crank sensor if not let me know and I will dig one up
Thanks for the update Martin, Sorry to hear the bad news. Might be less money to do a used engine swap if it is decided to fix it. Hope you have a great afternoon.
