1984 300D injection pump trouble? please advise
I have a 300D with 250k. recently the car wouldn't start or try to fire up at all until you shut the switch and try a second time and it fires right up. this is a recurring problem but it will always fire right up on the second try. The fuel lines have been replaced a few months ago all the way to the tank and there are no fuel leaks anywhere so I figured the lift pump might be loosing its prime and I tried a little experiment. Before starting up in the morning I used the hand primer pump about 10 strokes and she fired right up first try.
