Alright guys, got this in from another garage after they put a second hand head on it and it will not start. The story is they got it as a non-starter due to the timing tensioner having let go; they put a new tensioner on and it locked the cams up so on went the replacement head. It will start on a sniff and tick over all day, not well though, if you try to rev it up it cuts out. Oh and there is loads of white smoke when its running which apparently means its massively over fuelling!! For this reason they've tried 3 different sets of injectors before finally bringing it to me because we've got that fancy Ford computer!!

My words were; its not over fuelling, if it was you would have black smoke not white, RESPONSE: "it smokes all colours pal trust me" Well going on everything you've said i would say its a timing issue, RESPONSE: "impossible we've checked it 6 or 7 times because we thought that too but it pegs up fine and we've got the proper timing kit for it too." Ok leave it with me.......

There are no DTCs, so I went straight ahead and scoped cam/crank; I have a known good but only as a picture so its quite difficult to see properly, but, I reckon mine is fractionally out; not by much which is why I'm struggling to compare them and this would also explain why the is no DTCs set.

Does anybody have a known good as a psdata file so i can measure them properly please, and i would like to know your opinions as to whether this small amount would cause a non start?

Knowing these guys as i do when they say "we put a tensioner on it" that will be exactly what they mean, no new chain or guides in sight, therefore im obviously suspecting a stretched chain issue here

here is my capture taken during cranking http://www.mediafire.com/?0gr8je3nw1hycn0
