On my 1997 350 tbi there is no power going to the fuel pump. I have changed relays and still nothing. THis all started after pulling the transmission and changing it. I dont know what else to do. Could it be the oil switch? It looks ok cosmetically but I dont know. Please help.

The gray wire is power to the pump thru the relay (when energized). Power comes from the ECM B fuse in the underhood relay box. This power thru the relay is only there for 2-3 secs when the key is turned to the run position.

Jump 30 and 87 at the relay and then check for power at the pigtail.
