2. The spring valve on the oil pump is set incorrectly.

In order to eliminate option 1, I need to crank the motor and bleed the oil pressure line at the gauge. Loosed the oil line with a rag ot remove the air.

That's what we are planning unless there is a better way.

It's possible that the gauge is bad. One option (before getting into the dash...which is a pain in the rear) might be to try and rig something up to check the pressure at the engine to validate the accuracy of the gauge.
