No oil delivery points to bad pump. The fact that now it won't lift with air pressure points to something wrong in the control valve or cylinder. So you are looking at a few possibilities:

  1. The pump itself is not working
  2. The intake control valve is not opening preventing the pump from getting intake oil supply
  3. The exhaust control valve is not closing preventing air pressure from actuating the ram
  4. The ram is not sealing
  5. Any combination of the above

I would probably focus on numbers 2 and 3 first.
