Like states above, your symptoms point to a faulty crankshaft position sensor. We replace at least 1 a week at the Benz dealer I work at. It picks up the starter ring to see TDC cyl#1 and tells the ME to fire fuel and spark. If the car is cold, the install takes 20mins max. The sensor is held in by 1 10mm bolt on the engine near the trans bell housing.
