Conversation Summary

The owner of a 1991 Toyota Pickup reports the fuel pump is not receiving power. Jumping the FP port in the diagnostic connector to the battery allowed the truck to start, but it would not stay running. No power was found at the center of the air flow meter connector or at the E1 diagnostic port. Experts recommend checking the fuel pump fuse and relay, the EFI fuse, and the circuit opening relay.
