1990 4runner 3.0 fuel electrical issue
1990 4RUNNER 3.0L 160K
ISSUE - CRANK, NO START
HERE ARE THE THINGS I KNOW OR HAVE DONE: WHEN I JUMP DIAG PINS B+ AND FP, TRUCK DOES NOT START. I HAVE POWER AT THE FUEL PUMP CONNECTOR LOCATED UNDER THE REAR SEAT. WHEN I PROVIDE POWER TO THE FUEL PUMP (FROM AN OUTSIDE SOURCE), THE VEHICLE STARTS AND RUNS FINE. I'VE SWAPPED OUT THE CIRCUIT OPENING RELAY WITH A KNOWN GOOD RELAY. I REMOVED THE PLASTIC COVER TO THE VAFM AND EVERYTHING SEEMS OK, I EVEN DID OHM TESTING AND ALL WERE WITHIN SPEC.
IF YOU NEED HELP HELPING ME, I FOUND A GOOD SITE WITH A LOT OF GREAT INFO AND WIRING DIAGRAMS

THANKS!
