Hi guys I'm new to forms,

I have a 2005 C320 and I try to start it and nothing happens but all my lights radio dash etc all light up and work but it won't turn over at all but the fan turns faster then normal but won't start. It started random and have no idea what or why. Battery is 100% charged and won't even start while jump cables are hooked to it.

 

Starter or starter relay.

 

It was the ECM and SAM system $2400 for parts and labor at the dealer.
