2002 WJ Cranks but doesen't start
This is a strange issue. When I turn on the key, after a second the only lights lit on the dash are the key slash through, seatbelt and fuel warning light, no gauges like normal. Doing the on of on of on of on doesn't show codes like normal.
Replaced the crank position sensor, pulled all of the PCM/ECU connectors and large bulkhead connectors and cleaned with contact cleaner (although they were very clean already), new battery and alternator, full fuel tank, checked every fuse, swapped relays around (with like kind), checked every ground, added giant ground from the engine to the chassis just for the heck of it...
It dies on my wife, I pulled the PCM fuse in the power distribution block, cleaned it and put it back in and the car worked for another couple of days.
Now however it won't fire no matter what, including leaving the negative cable off for hours at a time.
Seems like the computer has given up the ghost, but I don't want to shell out for one if that isn't it.
Help please. It is my wife's Jeep and her elderly mother is entirely dependent on her.
