93ChevyZ71

Hello, I have a 93 Chevy Z71 and it was turning over, but not starting. Had spark, so we checked fuel. Dropped gas into the TBI and it started so our problem is fuel related. The fuel pump was not priming when opening the switch, but it worked when we sent current to it ruling the pump out. No blown fuses. Replaced the relay and It only “clicks” when we send current to it. Checked all the wire fuses on the power rail and they all had continuity. So we figured it was ECM and we just replaced it and still the fuel pump doesn’t prime and the relay doesn’t click on opening the switch. Our next guess is the PROM chip inside the ECM housing. Can anyone help with some ideas? Thank you
