Sense taking the pump off is not a difficult chore, I'll suggest pulling it and submerging it in a container of Hydraulic oil. Turning it back and forth while submerged, will get all the air out of it. Now try holding a thumb over the pressure port, while turning the input gear. Even a really worn out pump will produce modest pressure this way. You should be able to feel the rotation of the pump gears as they move fluid. If there is none, the top pumping gear may be free on the shaft. If it is, it will not pump. There may be a way to pin the gear, or have it machined for a drive key. I have seen this happen, and it is rare but difficult to find. Sticking a wooden stick down the port and turning the drive gear by hand will also point to this problem. Do not use the engine to rotate the pump with a stick in it! JimN
