Why is your Mercedes starting up and then shutting off?

Your mb is starting and shutting off after just about a second right? The problem is your fuel distributor. You cannot repair them coz it is a precision mechanical device that is very accurately calibrated to decimal tolerances, besides, it has a sensitive rubber-silicone diaphragm in sandwich between the four spring loaded atmospheric pressure balancers inside that small unit.
