well.. here's the deal. you resleaved the pressure tube right?
you didn't somehow block off the suction tube did ya?
if you had blocked the pressure.. it would be obvious.. it's befor ehte relief.. so something would be spraying and loading the engine.
pullthe plug out of the top of the head of the pump and see if there is oil there... probably not id my guess.
pull off the pump manifold and check to see if you can get oil to free-flow from sump to front of trans thru the pipe. if ot.. there's your problem. if it flows out like it should.. check the manifold for debris. if none.. it's now time to check the pump
ps.. make sure she is spinning.. look at the nose with the tach disconnected/
