Hi all. So I've never had to post before as I've always been able to find answers to questions just by searching. However, I've got a specific issue that I am hoping to find some info on. My 96 XJ totally cut off while driving on the highway earlier in the week, no warning. Pulled off safely, tried to start it again and it turned over but would not start. No check engine light, visual inspection looked fine.
Had to have it towed to a random shop nearby as I was a ways from home. They first believed it to be the Crank Position Sensor. I had replaced this with one from the dealership about 4 years ago but told them to give it a try. Nope. Come to find the rotor in the distributor was fried. They now believe it to be the PCM. Saying there is no '5 volt crank signal' being sent from computer. They are currently trying to source a new ECM. I am not so sure about all this. Has anyone heard of such a thing? Any info would be greatly appreciated before I run up a bill. Tempted to have it towed home to work on myself.
Most recent work performed - In March 2021 - upgraded alternator to 130amp - upgraded all grounds and battery cables to 2 guage - full tune up including ign. coil - changed injectors to 4 port. Jeep had been running wonderfully until that single instance.
