Hi, My SLK always started first time. Now sometimes I have to turn it over for upto a minute before it starts. Once started it is fine. When the engine is turning over it sounds like there is no petrol. I also notice today that the courtesy light did not come on when I opened the door. However when it had started I opened and closed the door and the courtesy light worked OK. It seems to be worst when cold. Has anyone any ideas? Thanks, Andy.
