Thank you for the quick response. I didn't get a chance to work on it until today. I removed the side plate as you stated. The 'valves' in there are working fine. I sprayed them with cleaner and replaced the oil in the injection pump anyway. After reading through the Operator's Manual again, I found an illustration that says the pressure at the injectors is normally 2700 lbs per square inch. However the illustration is of the Distributor Pump not the In-Line Pump which I have. Even if this isn't the right pressure, there's hardly enough pressure at the injectors to blow my finger off the line. That would be considered 'weak' right? Could the 'regular' fuel pump not be suppling enough fuel to the injector pump causing this? or is the injector pump itself shot?
