Jeep yj fuel pump wiring diagram

I have a 1991 jeep yj with a fuel prob how can i test for power to fuel pump to eliminate electrical and focus on pump?. Hey all, I'm looking for help identifying the wire that powers the fuel pump for my 93 YJ. I'm swapping a 5.3L in and the original PCM, relay block, and fuse block have been taken out.

Rather than switching your hot wire to the fuel pump, you could switch the ground. On your Jeep the ground wire for the fuel pump will either be at one of the mounting studs to your emergency brake, or to the ground stud on the right side of the engine block at the base of the oil dipstick tube.. The 2.5L has a relay for the electric pump but it's fuel injected and the relay is controlled by the ECM for safety reasons. Part of that harness you have probably covers all engines at the time. Here's the 89 YJ with the 2.5L wiring diagram with the electric fuel pump.
