I have problems with a vito 110 CDI. To cut a long story short we took the engine out and replaced the head. Put it back in and we couldnt get it going. it turned out to be a faulty injector which was replaced. it did started up but there was no power. EDC light is on so i made an appointment to get it code read but on the way it died all together with a klunk so it had to be towed back to base. there it wouldnt start at all, it does want to start but it wont fire up. any ideas chaps?
