    Looking for an ECU for a 1992 XJ 4.0 6cyl manual, california emissions

    This is a 1992 - Cherokee XJ ? the FP gets 12v from relay NOT PCM? The FP is not constant power unless engine running... The ignition gets power from relay... We need to get you some wiring diagrams something is making mental picture cloudy.

    Help!! Whistling when going up hill, loss of acceleration

    Pretty sure 1992 is OBD1 std Chrysler system and key trick should work . 1992 Is not the earlier RENIX system. Fuel pressure is a BASIC check for all fuel injected engines. A ruler to measure. Cut the wood a saw. Drive a nail a hammer. You will need tools for auto repair - guessing...

    4.7l v8 cylinder heads

    I do not think you have a problem with grounds - more likely a power feed ie coils or inj. on bank 2. The coil for cyl 4 is a clue. Look at diagram confirm which fuse - #6 is a 30amp and a major circuit - ASD is the main circuit for jeep.

    I was asking 54cj3b - maybe he saw a clue I did not. PCM is way way down the list of suspects. Fuel pump and pressure. Is pump staying on after @2 second prime- this is my "guess". Yes could be ckp watching fuel would be a way to confirm. OR a wave form - I did not think an option for...

    4.7l v8 cylinder heads

    Are you using a scanner ? I am thinking a chain incorrectly installed would cause timing issues and set correlation (sync) codes. And the scanner could show offset. let us know. Maybe a scan and post all codes.. Look at live data - ECT, FT's, MAP, TPS, o2 voltages, and finally...

    jeep wont start, no fuel pressure, changed fuel pump, still no pressure

    ideally you want a fuel pressure gauge to do checks. Always scan for code even if light is off. I will guess a 4.0L - let us know if you can trouble shoot elecs. use a wiring diagram and a test lamp.
