I've done a lot of searching and reading on this site, but I haven't posted any so let me give a little background. I have a '91 XJ with the HO and AW4 tranny, they were wore out when I got it so I found a '89 with a good engine/tranny and bought it for parts. I used the 89 short block and tranny, the 91 transfer case although I had to swap input shafts due to one being 21 spline and the other being 23 spline, I had the HO head rebuilt, swapped over all accessories and sensors and slapped it in. It purred like a kitten after ironing out a couple of little bugs after starting it, but when I took it out for the maiden voyage this past Sunday it didn't go so well. I drove it around for a couple of hours, which included trails, steep hills, and mud and then we stopped to build a fire. After sitting at the fire for about an hour it wouldn't start, no fire from the coil, so my buddy who is a mechanic by trade and I started troubleshooting as best we could in the middle of nowhere. We thought we narrowed it down to the coil (didn't really think that was it) or the crank position sensor so we set out to get the parts. Put them on and nothing still, turned out to be the distributor pick-up coil, or I guess what some call the cam position sensor which by the way does not exist on this model. Oh yeah, and this problem was somewhat intermittent because after we gave up and he started pulling me out of there to my truck and trailer, I kept trying to start it and on about the 8th try and after about 30 minutes of towing it fired right up. We drove around for about another hour and 15 minutes before it suddenly quit again and I never did get it started again until I fixed the problem.
Just wanted to post my findings on this problem since this is fairly common on these. :cheers:
