zero oil pressure WTF?
Common sense says it is the oil pump but I have read about sensor failure. I'm not about to run it but is there another way to check oil pressure? I'm open to any suggestions. Thanks in advance.

PM Ja03C5 he might have an answer for you. He found his wiring harness melted. After he replaced numerous oil sensors. That is all the info I know, I'm sure he'll be glad to help you with the rest.

If you had no oil pressure by the time the gauge showed zero you would have been experiencing other symptoms, such as ungodly engine noises. Faulty sensors have been extremely common, I had it happen myself. I'd bet it's most likely that. It's not too difficult to replace. Unfortunately it's in an inconvenient place to get to.

Wouldn't hurt to stick an oil pressure gauge on the engine and check the pressure. If you have pressure, then it's either the sensor or the circuit. It's always a good idea to verify that you actually do have sufficient oil pressure before assuming it's a bad sensor.

That's what I thought. 130psi. Can it read zero when it fails too? Did it also throw warning lights and a DIC message. I bet the ECM would not allow the engine to run if it was reading zero pressure too. I don't know about the LSX, but the LT-1 had a separate sensor for the ECM and the gauge. If you have a good scanner, you could plug in and see that the ECM is reading.

No it doesn't. ZERO when mine failed.
Scared the crap out of me too as I was booking it.
Even if you put an external pressure indicator on it, your gonna have to start it, or at the very least turn it over till it builds pressure.
I guess you can disconnect the coil packs to prevent it from starting.
I didn't (lucky or blessed?) and it ran fine, just no pressure indicated.
Bad sensor.
My heart started beating again once that was determined!
