I have a full rebuilt ls1 all internals are new. Oil pressure sensor is reading Low pressure checked. The pick up tube O-ring and it's good and I'm correctly and oil galley plug is new. Can't figure out what is wrong with oil pressure.

Put a mechanical gauge on it to make sure it isn't your sensor. Next, make sure you have the right spring in the oil pump.

Then(hopefully not), bearing clearances.
