The problem with 0 oil pressure for any length of time is there will almost always be rod bearings that are shot ,,,,,,,,,,,,could be o-ring , pressure relief piston/spring stuck or there's even a possibility that the pick up screen inlet is too close to the bottom of the pan ,,,,,,,although not real likely,,,,,,,good luck

Like mentioned...Doesn't the signal go from the sensor to the ECM and to the gauge?
Like others said, put a independent stand alone gauge on it. You need to verify you actually have zero pressure.
I don't see it being an O-ring issue or bearings. If the O-ring is pinched from the get go, low pressure would indicate so from the get go. The bearings too...have you ever seen straight up ZERO pressure from a bearing issue? Usually just very low.

There's a difference between no pressure and no volume. No volume will kill a motor in short order. No pressure but getting adequate volume and it should live.
OP, get a mechanical gauge on it before you do anything more. You can get em at the parts store for cheap. Run it between the hood & cowl and you'll be able to watch it going down the road w/o cutting holes to route it inside since it's purely temporary.

I've seen very worn bottom ends carry no measurable pressure at idle and barely more than 10 when wide open. Amazingly they held together. One took an open n2o hose into the air box to pop.

Any updates OP?

so...everything was put back together...great oil pressure...you replaced the OPSU at this time...then pulled the intake for new gaskets....then put the intake back on? so all your oil pressure problems started happening after you replaced the INTAKE? right by the NEW OPSU?
guess im unsure of what/how you did this, but to me it sounds like you may have messed up that opsu....or maybe your new opsu is a pos...
like others said, get a mechanical guage on there and verify it isnt the opsu or your gauge.
