right checked again.
I have checked all 4 plugs attatched to their individual lead and earthing them aginst the engine, they all have a spark coming to them.
the plugs after endless turning over smelt of petrol and were damp with fuel.
My dad reckons cos i took the rocker cover off and the plugs out, the engine has lost its compression sorta thing.
He thinks it needs to be tow started as its getting fuel an spark.
Also when u keep turning it over, it makes a bang sound in the engine bay which sounds like a release of pressure
sometimes u get a little puff of black smoke an soot just from around the turbo downpipe bolts
and when i turn the key off to take it out u get a puphh or puhh kinda pop sound from the exhaust
any more ideas
cheers again guys
