Well, I think I finally fixed her.(':D'), (':D')
After weeks of mindless and expensive repairs I traced the fuel starvation problems.
A vacuum was being formed in the Fuel Tank, although I went to this option first and ignored it then.(':evil:')
It seems that the Fuel Tank Vent unit (Top of Tank Rear) was clogged (But working somewhat when perfectly horizontal) and also the Fuel Cap Rubber seal was in wrong place, blocking the small hole (Cleaned this also).
The van wouldn't start when left overnight (Always parked on a slope) as it seems the fuel it was being sucked back to the tank.
I first ran the engine straight from a 2 litre drum (milk Drum) to the Injector pump inlet and the return also into the clean drum, it got me thinking, the problem is in the fuel tank or lines.(':idea:')
I replaced the tube from the Fuel Filter to the Injector Pump with a clear 5mm (ID) polyurethene tubing and reused the end fittings of original tube.
This was real helpful to see if it was sucking air through the system, its staying there now and would recommend anyone that has starting problems to do it .
Its a handy tell-tale to see if the fuel is draining back overnight to the tank or air in system.
I think that some VW/Audi TDI engines fit this as standard.
Just a warning, if you suspect that the injectors need replacing, do it asap and go to ebay.
As I was in a serious bind, I paid a Ford garage 400 pounds (160 euro, 00 pounds for each injector) .(':x')
You can get them on Ebay for 25 quid and takes 1 hr to fit.
I won't make that mistake again, or go near a Ford Garage for a while.

I found some great tips on this website and also here:
