Ok heres what happened. I was driving on the interstate hit a bump in the road and the jeep died -engine quit- every thing else works as far as i can tell. Engine turns over but will not start. started checking fuses and found the F6 30amp maxi fuse in the power distribution center (PDC) was blown. tried to put another fuse in and it blew immediatly. my owners manual and my repair manual dont tell me anything about what circuit that fuse services. I tried to trace the wire and the best i can come up with is there is a short somewhere between the fuse and the PCM. Any help would be very appreciated as i was supposed to take it on vacation monday AM. AS of now its staying home and im taking the quads only.
