disco 200 tdi not injecting

Bought a 200 tdi in good runing order, took engine out and dry stored for about 12 mths.
just put in new motor, but it wont start no fuel at injectors.
Plenty of fuel geting to pump, the solinoid is working fine took it out to be double sure.
i think some thing may have got stuck or gumed up while in storeage.
Anyone got any ideas, a diagram of the pumps guts would be good.
thanks

if you do a search on here for "pump tweak" im sure there is a good link with a good diagram of the pumps internals.
