I have a 95 Mercedes C220, I have a key that turns on the ignition and the instruments come on but it will not start. I jump wired the starter & it turns over. Does this car come with a security system, and can I bypass it? I bought it as a non runner.
Do you
have the same problem?

I would call the dealer and give them your vin to see.

I would start with fuel pressure check, spark test and compression.

No security light on, I thought the car might have a special key.

I found no fuel presure, I'm also checking the relays, and now will check the fuel pump.
