Newbie needs help on fuel pump problem

I bought a 92 runner with 3.4 swap. Been running awesome for 10k miles with no issues. now, engine cranks and sparks, no juice. I checked the diagnostic for the B+ to FP jump to test. No FP pin! ouch. Checked all connections/fuses. Decided it was fuel pump and moved on. (242k miles on it is a good guess). Pulled old one, connected to 12v and runs. I have been reading on here that it is a COR or a fuel pump relay switch. Are they the same thing?? Which do I replace?? (I found one saying fuel pump relay under dash on driver side) and I read that there is one passenger side rocker panel.
Any other ideas?

No telling how yours is setup since someone may have changed things but the stock location for the cor (yes fuel pump relay and cor are the same thing) is above the passenger kick panel. Remove glove box for access.

Should be able to verify its operation, or fault, once you get in there. It should energize the relay when cranking and running. Pretty simple setup. A wire from the ECM will send ground to relay when the ECM wants the pump on, power in( at two spots.....one for relay operation and another for power distribution ) and an 12+ output to the fuel pump.

I put some pictures of everything in the 3.4 saw 101 sticky thread at the top of this forum.
