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. 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. If this solenoid is sticking in the off position you can have the problems you experience. When you hit the engine with a shot of ether you have supplied fuel to it and the engine vibration probably causes the solenoid plunger to release. This is just a guess and again an assumption. In this case you would be best replacing the shutdown solenoid and not screwing around. Citing the engine does start and not shut back down until you want it to lends creedance to the ignition switch is supplying power to this solenoid. The same scenario could play out with a manual cable shutdown also if it is out of adjustment.

hello

what tap on the actuator on the fuel pump mean? can you explain?

thank you very much

Generally speaking an electrical component that smokes is usually no good itself, or a component it supplies current for has gone bad. In you application I do not know for sure. Mack did in many applications use a large, round metal cased contactor referred to as a power relay. These usually audibly clunked upon turning the ignition key to the run position. Electrical power was then routed throughout the truck via this contactor.
