hello all, I work at an independant repair shop specializing in Imports, mostly european. We have an 01 SLK 320 that we are having trouble figuring out, and I figures I would post on here and se if you guys had any ideas. like I said its a 01 SLK 320, the car will not crank at all. We have replaced the crank sensor and the Pulse circut starter relay, but the symptoms remain. Any of you guys got any ideas? thanks in advance for any help you can give.

 

what have you checked? Is the starter getting power, when the key is in the start position?
