I have a 1999 ML320 with a 135,000 miles. Sunday it would not start. With the key inserted and turned to position 2, only the SRS light would come on. The engine warning lights did come and the key operated accesories did operate either, ie door lock, windows. The battery is only six months old. I tried both keys, thinking it mite be the anti start circuit, but no luck. The car had been running good.

Anybody had this problem? Or any suggestions on where to start.
