I took out the heater plugs and turned over the engine first thing to see if the injectors were actually injecting diesel and sure enough there was plenty diesel vapor spraying from the plug holes,

I had a good crank signal, the injectors were firing,glow plugs working,good compression.so i said is there any chance the timing could be out!!

I had to remove the air intake manifold then the top clover and got out my timing tools and check it,,

Sure enough the cam timing was out by 180 deg.

When it ran on sniff,( it can if the cam timing is exactly out by 180 deg) and when i was told the cam timing is 200% correct i over looked it!!

I should have known better at this hour of my life not to trust no ones work unless i see it done first hand myself,

Another day another lesson,

Many thanks to you all do for your help full replies,
