If it's too hard to find, here's a link. Mods need to tidy up this joint.

I'd prefer to not clutter up the OP's thread anymore by going off topic, so I'll leave this in an edit.
By being off topic you are not contributing to helping the OP, who made this thread for a reason, not for you to get your kicks from arguing and BSing.
It would do everyone a favor if you and others could stop being ******** and adding misinformation.

My fuel pump is not priming when i turn my key. While diagnosing the problem, I got the pump to prime and build fuel pressure by bypassing the fuel pump relay so I know the pump works. The fuel pump relay isn't getting a signal to turn on the fuel pump. Does anyone know what the possible causes might be?
Good luck anyways bud. Perhaps checking in with a local guy to help you fix your problem.

Ok, here is where you are wrong. It is not about being a winner or loser, or getting into a pissing match over the biggest dick.
It is about giving correct info, seeing as how this is a TECHNICAL forum. Any wrong info should be immediately dismissed. It only hurts the OP by giving bad info.
It's already been shown that oil PSI has nothing to do with starting or the PCM.
How many times must it be said before you realize this?
I haven't wandered into the LT1 section for a year cause of all the ********* and I decide to start reading and posting and it's got even more of you guys than when I gave up.

Nothing to do with it...blah, blah, blah...

I have had the same problem lately, car stalled out after work, i went to the relay and put bullet connectors on the wires and drove home. The next day i put a pressure guage on it, it started and built pressure and the lost it. I did not see where u have replaced your relay but that is what i did and it is a place to start. You are talking about the relay behind the drivers kick panel right? I left the bullit connectors in place in case i need it to bypass to get home.

You pose an interesting point, but it looks like even if that switch is flipped, it has no effect on the circuit the FP is on at all. Plus it splits off a 12 V line from the PCM and goes back into the FPR line, which has it's own independent power.
Since it says switch, it must be something that is activated manually or mechanically.
The psi sensor is simply a pressure gauge with a diaphragm that transmits a constant variable signal, no switch at all. A switch is either ON or OFF.
Just because you can show me a diagram doesn't mean you know what it does.
I'm not sure of the legitimacy of your BP but here's one from a manual, specifically a 94 LT1.

Boy, this thread took a bad turn, LOL.
Right. Nothing. That diagram is not for an f-body. Corvettes used an oil pressure switch, but it was for keeping the pump running when oil pressure was ok, in case the f/p relay died while driving. F-bodies don't have this.
Sorry, you bet on the wrong horse.
I think the word you are looking for is shboxed.
