fuel pump relay

on a 92 yota pick up where is it located, didnt find any thing under the hood in the big black box . truck is stock 140,000 miles no power at the pump no blown fuses any help would be great

its under the hood in that big black box theres to black relays, one is the starter, one is the EFI system. you can try swapping them and seeing if the truck still cranks....if it does you know the relay is ok (doesnt mean the wiring is ok). The fuse right next to it is the EFI system fuse...15a IIRC, double check that too

yea i already checked all that stuff ,also tried tracing the wires as far as i could didnt find anything there either .starting fluid in a vacume hole will let the truck fire up so everything seems good just no power at the pump any suggestions.

circuit opening relay was bad
