C280 1994 Starting Problems
 

Symtoms:

1) Approximately 95 % of the time it takes two or three key turns turns to get the car to start.

2) Approximatley 10% of the time the key lock cylinder will not move until "jiggled" a few times.

Replacement parts so far

1) Wiring harness

2) Crank Sensor

Suggestions, please.:confused:

Thanks,

Over Voltage Protection relay....a common cause of hard starts and the relay is known to fail with age due to dry soldered joints...if your car is still on its original it will fail....its only a matter of time.

I now replace them as a matter of course every time I get a M104 engined Merc, as prior to that they always used to give me trouble.....easy to replace and cost about $60
