As the title says, I can't get my oil pump to prime. The oil pan is full of oil. The pick up is 3/8" off the bottom of the pan and screwed in tight. The pickup and tube was checked for obstructions before being installed. I installed a new timing cover, adaptor, and gears. I put vaseline around the gears to help in the prime and spun it over like a muther with a 1/2" drill on hi speed trying to get that thing to prime. Nothing. Pulled out the relief spring and plunger, cleaned and re-installed. Still nothing. Any ideas before I pull the motor out again?

Thanx.
