I have fuel! My dumbass wired the fuel pump backwards. The replacement one was totally different than the original and the poles were not labeled and in opposite positions as the factory. Probably should have bench tested. Last problem is still that the key in ON does not seem to actuate the fuel pump. I am assuming EFI relay at this point, but it seemed to check out on a bench test.
Yes. But now I'm back to the first problem I had where its immediately blowing the EFI fuse. This is such a pitaWhen you turn the key on but not far enough to crank the engine does the CEL illuminate? If not then the EFI main relay is dead.
The fuel pump only gets power when the starter is engaged or the engine is running, not with ignition on.I have fuel! My dumbass wired the fuel pump backwards.

Yeah, I need to get one. Just figured this was pretty simple.
@CenTXFJ60 found the issue later. ARB compressor bracket was pinching a wire causing it to short.Following along. My brothers 62 developed this exact same scenario while in Ouray this August. We followed the wire diagram and tested every connection related (and mentioned above) and no luck. Finally swapped the ECU and it fired up. We still knew the problem had not been identified as something caused his original ECU to fail. Truck sat the last few weeks then my brother pulled it into the shop Saturday to change the battery terminal connectors and bam…the dam fuse is blowing again every time we turn the key on. We have spare EFI and COR relays and have played with every configuration. We even disconnected all the electrical ads-ons since he’s owned it (compressor, stereo, LED lights etc…) and no luck. I’m at the point I may pull the harness, inspect it ( repair if needed) and reinstall it.
