Why does my diesel engine start then die?
It’s designed to stop fuel flow if oil pressure drops and of course until the engine runs for a couple of seconds there isn’t pressure so they ignore that sensor.. When they fail (or your engine fails to build enough oil pressure) then it will start, then shut down.. Usually should allow restart almost right away though
