do you have an immobiliser fitted? do you have remote locking and a silver sticker stuck in the windows declaring mecedes approved alarm system fitted, or some such guff? i presume it is cranking over ok. possible immobiliser fault or ovp relay.

OVP relay, its next to the battery the one with the fuse on the top, pull the OVP out with the battery connected and plug it back in again, the car should then start.
