freedomsr40

Hey guys i am REALLY hoping you can help me. i purchased a 2000 clk 320 the other day and drove it home. i even moved it around my yard afew times with no issues with starting. It has a check engine ,srs, ABS and ESP light on. i read up on these and found that a fuse could be to blame for the ESP light . With that said i changed the SRS fuse as well as a couple other fuses (ones i thought may be related) and i went to start it and i have nothing... i hear one click and that is it. i tried disconnecting the battery for a bit, made no difference, i tried switching the relays ,nothing, i checked the other fuses and nothing. i tried jumping it, nothing. what happened? i had just had it started an hour or so prior to this...HELP!

Fully charge your battery and replace the brake light switch, which is a common replacement item on Mercedes. Jumpstarting a Mercedes, while it can be safely done, is really not recommended due to the sensitive electronics, particularly the anti-theft.
MB Medic has a good article on a no-start Mercedes:

There's a lot of articles on the web about the ABS, ESP, and the brake light
