1020 Hydraulics

[Jbuys62]

I have a 1020 that I have used for a few years. About a year ago it developed a slight noise and a vibration by my right foot. Earlier this year the hydraulics quit on me. The loader was very intermittent, the power steering as well and the 3 point did not operate at all. I was going on an extended trip so it sat for the summer. I had my son in law order a new hydraulic pump and just installed it this week with the help of a friend. I also cleaned the screen, new filter and fluid. I removed the spark plugs on the engine and am rolling it over with the starter to prime the pump but I don't seem to be getting pressure. Do I need to get it running or could there be another issue? My son in law works for a hydraulic shop but I don't know if anyone knows about this particular tractor as they work mainly on boom trucks and the such. Any help would be appreciated and as a side note, I have hernia surgery next week so it might be a while before I can tackle it.
