Crown vic keeps burning #12 PCM power relay fuse, the car turns on but within a couple of minutes it burns the fuse and the car shut off and won't turn back on. we think there might be a short somewhere but have not be able to locate it.Could it be something else, a coil perhaps?
Have fuel pump checked i have known a bad fuel pump shorting out causing pcm fuse to blow.
Was burning out #1 (of 8) ignition coil... new coil burns out again in less than 5 minutes running... will check sparkplug condition to see if damaged... see if getting sparking current or steady current... I replaced the 30 amp fuse with a 30 amp auto-resetting mini circuit breaker while diagnosing... the circuit breaker never popped as far as I know, but two ignition coils on same cylinder burned up...
Had this same problem i thought it was the fuel pump it but it wasnt was the o2 censor wire burnt to manafold check all wires before changing pump
There are two fuse boxes. A baqttery junction box under the hood on the drivers side and one inside on drivers side. Good luck.
