I have traced a hard start condition to what I think is the cause. The
hand prime pump allows air into the fuel system. Today after the car
had sat for 4-5 days I used the hand prime pump for about 20 strokes,
could see air bubbles pushing through the clear plastic bleeder tubes
between injectors. The hand pump was leaking fuel that spilled down
the side of the engine. I then started the car, it fired right up so I
feel this pump is the problem. Some posts point to this as a cause. My
questions are: can it be done with the injector pump on the car? Can
anyone give me a blow by blow of how it is done? Can you seal the
existing pump or must you get a new one? Can I order this from any
Bosh dealer instead of MB? Any help or opinions are always welcome. I
have had great success here to solve other MB problems that haunted
me for a long while.
