Codes with proper diagnostics would help a lot. Crank/cam relation is usually caused by cam sensor if the engine worked fine and after restarting does not fire up. So how it worked before and now problem occurred? Also the age could help, are we talking about M57 or facelift M57N?

Yes tell the storey when/how did this start.
Also have you tried starting it with easy start or brake cleaner.
