I am also experiencing a problem with my 1995 C220. I have left the car with mercedes for over a week and they can't find anything wrong. The car will start and run wonderully one time, then the next time the car will just turn over and over and over, and not start. They say they have checked all the relays and there are no problems there. They have given up basically. They tried to say it could be my computer. I don't think so. One interesting thing is that when I turn my key to the start postion and allow my cars electric system to turn on, I hear what sounds to be the fuel pump turn on, then my car will start, even after many attempts to start the car normally. I am not sure if that information helps. Any help will be great. Thanks eric
