You have no pressure because in order for the pump to work it has to be primed, they sell a tool for that, but before ya go spendin more money, are you POSITIVE you have the right pump, and the drive for the pump is inserted and seated correctly, how are you reading oil pressure? Electric gage? is that working right? If you are using the original oil pickup tube make sure its not obstructed,if your using a new pick up tubemake sure there the same length. To make things a bit more complacated are your oil passages in the engine blocked? Engine stop leak is great for that! Hopefuly it only needs to be primed though! LOL Good luck
