1980 mercedes 300 cd Wont shut off Diesel?

Vacuum pump overhaul time! there is a red lever on the injection pump on the side of the engine with the word stop on it push it and it will shut off then find an OLD Mercedes tech like me to diagnosis the vacuum problem

i'm guessing in this yet I had a diesel(distinct vehicle make similar 3 hundred and sixty 5 days). contained in the engine compartment, discover the gas injection pump.(that is the position the fellow metal lines to each cylinder meet). On that unit, there should be some tremendous electric powered wiring. One singular cord lower than a small nut which, at the same time as there is skill(12V) going to it, holds the "gas shrink off solenoid" OPEN which permits gas to bypass into the engine. typically, with the help of turning off the major skill does no longer bypass there any more effective and the solenoid closes slicing off the gas. Engine stops. both loosen this cord off the nut ( or shrink off the cord-yet you favor to commence the vehicle later so it must be reconnected) Your selection what to do. hit upon slightly metric wrench and do it acceptable or no longer. once the cord is bumped off, the engine will end. Why no longer disconnect the battery? because the alternator will keep the skill going there. difficulty is both contained in the shrink off solenoid or contained in the ignition swap is worn. (In mine, it replaced into the ignition swap) let a keep experienced in diesels fix it.

fuel shut off valve is not operational
