Question about 1996 Jeep Grand Cherokee
Turns over will not start no gauges work replaced fuel pump fuel pump relay clicking could it poss. be ecm do not see ecm on panel
Sounds like a body control module --in most newer cars there is a ecm for the elctronics for the motor and a bcm for all the interior dudadds --Check EVERY fuse in the truck and out under the hood -- look up the wire color codes for the ecm harness --check the power wire going to the ecm for 12v --or jump a wire off the batt + to that wire to feed it.try to locate all the grounds also--if need be google it --Like my ls1 trans am has a ton of ground wires --but there are 2 on the back of the head--if they are loose it will not run even tho all the other grounds under the hood are tight.I think they do that to isolate the ecm from ground back feeds or cross wireing when jump starting.
