Electrical problem
1989 Jeep Comanche 6 cyl Two Wheel Drive Manual 180000 miles

Truck ran hot, shut it down to check. Problem. The truck hasnt ran since. Turns over and everyting but no power to distributor, fuel injectors, fuel pump, or anything. Changed the computer, fuel pump, relays, and it has been to dealer and they cant find out what is wrong either

Do you

The way this sounds i'd have o check to see if there is a fusible link on the starter. If it does, then it probably burnt up and that's why there is no power, especially since you admit that it got hot so it may have melted the link. It is there to protect the system. You would need to go to starter and youwould see smaller wires connected to bigger ones. That is the fusible link. If it's not looking like regular wire then it's bad. Besides if you have a test light you can tet to see power at starter cable then poke one of hte other wires to se if they have power. I am taking a gguess here as i'haven't worked on a jeep in a while. But it sure sounds like it.
