There are several reasons for no pump pressure. Either the pump is shot, the drive gear retainer sheared so it doesn't turn with the drive shaft, the pump is not recieving oil from the suction feed tube, or the pump outlet is unrestricted. (This assumes the mains and rod bearings do not have excessive clearanaces, etc.)
Make sure the suction feed tube to the pump has no cracks or bad seals and is not blocked. If it has a screen, make sure it is not restritced. Make sure that the relief valve is not stuck wide open or has a broken spring. Make sure the housing and the outlet are not cracked or broken. Makes sure the drive gear is securely fastened to the drive shaft.
