![]() ![]() If this solenoid is sticking in the off position you can have the problems you experience. Usually when these work correctly power supplied by the ignition switch releases this hold on the fuel rack allowing the governor to control curb idle. I'm assuming you have an electric solenoid mounted to the injection pump governor: This solenoid would pull the fuel rack that is internal to the pump to the no fuel position to shut down the engine by starving it for fuel. Now was that just luck or could that actuator be bad. ![]() So I got curious and tap on the actuator on the fuel pump and it started. ![]() Fuel filters are tight, no leaks on any fuel lines, it has a new drainback valve. It's wierd you spray either to it and it fires right up. We have difficulty starting it when it is warm and cold. I have Mack CH-600 with a mack 300 motor. ![]()
