Hi all I have a vito starting problem. i broke down just before christmas, the van started pouring white smoke out the back and pinking or going off a cylinder or maybe 2 one day. i pulled up along the side and the engine stopped and would turn over but not start. felt as if it was hydraulising a bit when i tried to start it. Anyways got it towed home and suspected a blown injector as i used to mechanic years ago and read up on the OM651 problems. Set of recon injectors in and it still doesnt start, no fault codes either. its virtually starting when i turn it over and actually did at one stage for a second or two but running very tamely or quiet. im really stumped as i mechaniced before all these fancy sensors and technology came along. i have an icarsft i980 basic scanner but cant see anything obviously wrong with the engine or sensors. Any help or pointers from mercedes techies would be greatly appreciated.
