94 pickup no click or no noise from fuel pump
My truck no crank or no sound from the fuel pump. Thought it was the computer so I tried another ecu same thing. Also checked the fuses and efi relay. Could it be the circuit opening relay? Anybody had this problem? Lmk any help is good.

Sure.
It seems there is a new discussion on this just about every day. I can't imagine how you could have missed this with the simplest of searches.
Start with easy stuff. Jumper FP to B+ and turn the key to "on." You should be able to hear the fuel pump. If not, almost certainly a bad pump (FP goes direct to the pump, but of course you could have an unlikely broken wire). If the pump is now running, your problem is in the VAF-COR circuit. (Don't go swapping out expensive parts, like the COR, at random.)
