Before I pulled my motor I had zero oil pressure. The oil pump is Milidon and has 150 miles on it. I suspect the oil sending unit and not the pump. I have the motor out of the car and the oil pan off. Would like to make sure before I put it all back together.

Luuuuke,
Go borrow an engine oil primer from autozone or kragen. Do what jeff said, if you have a gauge you should see it react from the test. Or pull valve cover off and watch for oil come up into top of heads.

Place oil pan or drain pan underneath the chucked oil pump to drill motor.
Submerge the pick-up in the oil.
Turn on drill motor for a split second to confirm correct rotation; reverse drill motor direction if needed.
Extend arms and squeeze trigger - watch oil fly to the ceiling, if in the garage/living room/kitchen ---- no oil, bad pump or drill motor in wrong direction still.
Place a plate over the pump outlet, C-clamp would be good.
Squeeze trigger and see if relief valve works - oil will coming out the side of gear cover.

Was the engine running? Did it sound OK? I don't think it would run long or well with 0 lbs of pressure. Probably the sender or gauge.

A little late but speaking as a 25yr journeyman mechanic the first thing you should have done is install a cheapo mechanical gauge to determine if the sender was bad or not. At this point I would remove the electrical sender and try to find a buddy to install it on his car and see what it reads. If your oil pressure really went to zero you more than likely need more than a new pump at this point :(
Anyone know how deep their crank is tapped for the balancer bolt? (differant thread but I'm still waiting for an answer:))

Good luck Lukeskywalker.

I want to say at least 2-1/4" to maybe 2-1/2".

Heck, might even be 3"??

Take a 7/16" x UNF bottom tap and tap away for a SB.

1/2" x UNF for a BB.
