I'm in the middle of fighting a PCM issue with my 96 ZJ... Will start fine... passes the wiggle test, and you can drive it. Sometimes it will run fine, and then when you get down the road, it will just shut off on you. No CEL... just *blah*. If you try to restart, it won't. Turn the key off, wait a few seconds, and try to restart, and most of the time it will fire back up and keep running... sometimes for a while, and sometimes it will die in a few minutes. Then there are times it won't restart at all. Gets fuel... no fire.... Computer doesn't report a loss of CKP or CMP, so I suspect the PCM.
Only code i get is a P0351. Replaced the coil. CKP and CMP are good. It's pointing to a bad PCM. So either I have to find a PCM in the junkyard from a running wreck, or shell out $650+ for a new PCM from Jeep. I'm a bit leery of the A1Cardone repops.
Looks like I am going to pull my PCM this weekend and pop it open. Have to make sure I take my tune off of it first....
But now I've seen the Regulator board issue, and the three main harness issue.... More to check....
