so far i have replaced the ckp and cmp coil, all relays, all fuses, and rotor, distributor is spinning when cranking, cap is in good condition. my instrument cluster randomly stopped working yesterday same symptoms as before it stopped working only now i really dont know if my cel is on. before i hooked a reader up and it said unable to communicate with computer.
"New part" doesn't mean "good part". If the reader can't communicate with the computer, the computer is NOT coming on. It's possible (but unlikely) that the computer itself is bad, but it's more likely that a shorted sensor or melted and shorted wire is causing the problems.
Do what I suggested in my last post, even though you replaced the parts. If you've got a code reader, plug it in each time too. If it says it can't communicate with the computer, the computer is offline.
Disconnect each and every sensor on the motor if you have to. CKP, CMP, TPS, IAC, Oxygen, Temperature, Oil pressure... The computer contains a 5-volt regulated power supply inside the computer that powers a number of sensors. When that 5-volt bus is shorted out, the computer doesn't turn on.
When it happened to me, I put together this spreadsheet with the computer pinout. It may be useful to help you diagnose a problem. I developed it from the schematics in the YJ/TJ Haynes manual.
PM me with your location. Cleveland-proper is a bit of a haul for me, but if you're in one of the more southern suburbs, I might be able to stop by sometime this weekend.
