xceth,

My opinion is U have a lack of fuel getting to the IP. Someplace there might be a air leak in one of the input lines.

Take the output line off the IP and while pumping the primer pump, determine if fuel is coming out of the IP. [I]f no fuel comes out, find out why.

Before U buy a rebuilt IP, Take your IP to a Bosh or Injection pump shop and have it tested. If there is something simple wrong with ur IP, it will cost much less to fix than buying a rebuilt IP.
