Mechanic's Assistant: Are you fixing this yourself? What have you tried so far?

We keep losing fuel to #4 cylinder, have tried 3 different cyl injection pumps after the original went bad at 930 hrs. They work for a short time and then stop pumping fuel to #4 nozzle

If you swap a working pump, with the one not firing, does it work, or does it also miss? If miss continues, your fuel supply to the injection pump is inadequate. Check the fuel supply and the suction system, to see if you are sucking air, and starving the # 4 pump.
