Priming 4a032 oil pump

[6x6TRex]

Anyone know how to prime the oil pump on a 4a032?

Got my Mep-016C back together today after installing a new cam, oil pump, and fuel pump. Got it running and ran it for ~2 min but am not getting any oil pressure! I had pulled the oil pan and cleaned the screen and oil passage in the pan and block, so why am I not getting any oil pressure!?!?!

I have the TMs but haven't found anything related to this.

i cracked the oil pump gear housing on one of these eng. and replaced the pump gears. no priming was needed. may want to take another look at pump shaft and cam.
