I have a 1995 E320, and all of a sudden it wont start. It won't even turn over. I turn the key and nothing. I checked the battery and it still has juice left in it. The dummy lights come on when I turn the key, but thats it. The starter does not engage at all. Like I sid this happened all of a sudden with no warning. Any ideas of what it could be, and where should I start looking. Thanks
