The pumps are also installed incorrectly in their bores or the body is disassembled and phased incorrectly into the housing. If these things happen it won't move any oil.

Well this sucks. I really hope I changed the clocking of the pump in the housing by mistake when I inspected it. I spun the shaft clockwise (looking at the shaft) in oil and it blew out oil from the correct port. I blew air into the valve cover pickup port and no blockage. I pulled the pan and blew air into the output pressure port and air came out freely from the drivers swirl pot.
