I believe this one is now fixed.

I'm sure Ian will be along soon to fill us in on the finer points.

Hi Mark,

Yes this is now fixed thanks to your help in educating me.It was'nt a injector as i suspected.
it turned out to be air ingress into pre pump not allowing rail pressure to meet the require 200 bar for starting .I replaced all the brittle 3 plastic fuel pipes
and also replaced the seals in the return pressure regulator. after doing this the rail pressure was up in no time at all.so thats problem number 1 sorted
Thanks again Mark
