Own a 1986 300E. Car died on me last Saturday and hasn't started since. Noticed I didn't hear the fuel pump turn on when I turned the key, looked at the fuel pump relay, noticed a few prongs were burnt. Replaced the relay, still won't start. Only hear the fuel pump very slightly(can hardly hear it), put test light on the fuel pump,getting juice, pulled gas line from fuel pump and turned the key off and on, very little gas came out of the line. Any suggestions?? How can you tell if the fuel distributor is bad? Does this sound anything like a fuel distrib. problem? Changed the OVP Relay in MAY/JUNE 00 any chance that this piece could have gone bad this quick? Does this even sound like this could be the problem? I doubt it but you never know? If anyone knows which fuse controls the fuel pump in a '86 300E please let me know. I believe I changed almost all of them..

Have you checked the ground wire of your fuel pump? I think the ground is shared with the ground for the electric antenna (in the trunk, driver's side wheel well). We had the same problem with my father's 190E, when the key was turned to start the car, you could barely hear the fuel pump work for about half a second. Afterwords, nothing. Once we found the groung to be loose, we tightened it. Then the car started without hesitation. I hope this helps.

The problem turned out to be the fuel pump. The one I just put in is much wider than the one I replaced. The ends were different,and even the neg. and pos. posts were positioned differently. Not sure if the one I replaced was a Bosch. Happy all over again!!!
