Heres the story. I have just replaced my rod and main bearings, and the oil pump. Got everything put back into place and started it up and it sounded bone dry. So I took out the distributor and primed the pump with a drill. I tried to start it up again and same results. Dropped the oil pan and made sure the oil pump had not come loose. Got everything put back together, primed the oil pump again, started again with the same results. Zero oil pressure and bone dry. What am I doing wrong? Is there a special way of doing this? Please help. I purchased a new oil pump with pickup tube and plan the try again on Thursday. Any comments that might help are welcome.

Do you have an oil pressure gauge installed? If so, what does it read when you have a drill turning the pump? Pop off a valve cover and see if you are getting oil there.

I had the same problem when I replaced my pump. Turned out that the gasket between the pick-up and the pump had slipped out of place and was blocking the hole. I took out the gasket and my oil pressure returned.

Be sure that you're priming it counter-clockwise, I know it sounds stupid, but everybody's done it before....

Ditto what everyone else said, but I must reiterate that you gotta see that oil flowing over the valves on all cylinders when your priming the pump before you start the engine up. The warranty on my longblock specifically stated that this must be done or you could kiss the warranty goodbye down the road.
