I am still having problems with my 1995 C220 starting each and every time. It will turn over but not fire up. I has left me stranded a few times. I have the car in Virginia at a Mercedes dealer. After ONE week, they still have not found out what is wrong. They say it has to NOT start for them to diagnose it. Why? If it is the crank sensor (as suggested before) can't this be checked even if it starts??
