Working on my 1996 jeep with a crank/no start issue that just happened randomly out of the blue one day. It does not get any power to the coil/distributor/cps. The engine cranks with the key but the ASD/fuel pump relays do not trip when turning the ignition on. Have battery voltage and ground going to the pcm. Have tried cleaning all engine/chassis grounds. Think maybe an ignition or pcm issue. Anyone have any input or wiring schematics I can follow? Thanks.
