Hey guys i'm looking at a 300D that has an engine knock. The guy said it made a funny noise and then he pulled over and cut it off. Now it wont restart. Any idea?

Not really a lot of info here, but it could be fuel-related, e.g. someone inadvertently dumped gasoline in there, or there's some water in the tank; or it could be an oil starvation issue, as in a rod bearing is going; or it could be a timing chain stretched too far. We need more info to help you make a proper determination.

The 3.0L OM603 dont have rod bending problems but head crack dose you car temp stays at 90*C or above, Look at STOP lever at the injector pump, when your ignition is at 2nd position dose it go up or dose it stay down, if its stay's down it's cutting out the fuel supply....
