I have a 2007 Crossfire that won't start. When I go start it it won't crank. I can try it several hours later it'll start. I've taken it to the dealership, left there for weeks at a time and it always start while there. I've replaced the starter switch and clutch safety switch, yet with no positive results. Any ideas what the problem might be? From November until yesterday it would start, yesterday nothing, this morning nothing.

 

Ground cable, RCM, Crank Position Sensor? Dealers know nothing. If it must go to a shop, your best bet is an Independent that knows Mercedes. It is actually a 2004 Mercedes SLK320.

 

The first problem was taking it to a dealership ... follow ZERACER's suggestions ... where in this world are you located? someone may know of a local independent shop .

 

Too many new members won't even list their state of residence. What is up with that?

 

Detroit.
