When I had the broken pickup tube, I was able to pump oil for a few seconds
when the pump was primed through the filter mount hole. As soon as that oil
was expelled, pressure went back to zero. If you are absolutely sure that
there is enough oil in the pan and you are turning the pump the right
direction, this is probably the time to pull the pan. Remove the oil pump
and pickup tube and examine them closely. My pickup tube broke on the top
of the casting by the pressure relief valve, inside the pump. This area is
not visible without removing the pickup tube from the pump. The casting is
very thin at this point, about 1.5mm. I sincerely hope that this is NOT
your problem.
