Default 2000 S80 2.9 no oil pressure, help!

Hey guys, have a 2000 S80 2.9 with no oil pressure, I have volume, but no pressure. I have replaced the oil pump and cleaned out all oil passages. What controls oil pressure? The car runs great, just oil pressure light comes on 1,200 rpm.

Have you checked and/or replaced the oil pan o-rings?

The oil pan O-rings help control pressure also between the top and bottom of the engine.
