96 Jeep Grand Cherokee Laredo 4.0 4x4 245xxx miles. was running fine, turned engine off , it has not started since. no pressure at fuel rail no spark at plugs , fuel pump never gets energized , not even the timed period after turning the key, can bypass pump relay and pump runs. At this same time the fuel gauge quit working low fuel warning stays on .
Have checked all fuses in the dist. box and the BCM
I have tried the short screws in the ecu, have pulled and wiggled the wire harness, switched the relays from other sockets ( known good ).
replaced the ECU with one from a wrecked ( not a junked ) vehicle.
what energizes or deenergizes ASD relay.
