I have our Oliver 1800 C back together and am ready to start it.  I bled the primary and secondary fuel filters and have fuel to the line feeding the injection pump.  The wiring is connected and the solenoid clicks when the key is turned.  However, I get no fuel pumped out of the pump.  

When we parked the tractor 18 months ago it the pump was working.  Should I jsut pull it off and take it to the Diesel Injection Pump Doctor?
