Hi knobby1, yes I have done that but still no luck , I think it might be the pump , so that’s on order and I will let you know what happens thanking you john

The pumps themselves very rarely fail....but sillier things have happened.

Have you looked at live data to see what the fuel pressure is when the faults occur?

Do you have any permanent or recurring fault codes?

I think you are replacing unnecessary parts rather than finding the reason for the running problems.

Have you carried out an injector leak off test? To confirm the injectors are all within specification?
It would not be the first time a new or reconditioned part is faulty before it's fitted.

Go back to the origin of the fault, when did you first notice it and if anything had been done before the fault occurred.

Good morning, after putting a new fuel pump in , it hasn’t helped me wit this problem, on Ford scan it’s not showing any codes so I am still at the same place looking for the problem , thanking you john

As Airthies said...loading up the parts cannon is pointless, time consuming and costly. The TDCi pumps hardly ever fail so replacing it was probably unnecessary.

What fuel rail pressure are you getting during idle..?? Were the pump, pilot & injector "learns" completed successfully..??

Were the SCV & PRV genuine Ford/Denso items..??

Good morning they are original parts and the pressure on the rail I will have a look and let you know when I get time to work on the van Thanks john

Good afternoon , I think I might have found the problem, after takeing the prv out again the copper seal wasn’t sitting right , dose any body know the muten meter on this to tighten the prv back in place as Ford here won’t help me thanking you John

The PRV is done up in two stages and the sealing washer should be replaced as it is a "single use" thing:

Good afternoon , lord knobrot thank you for this information , do you know if its possible to over tighten the prv and damage the thread on the rail? Thanking you john

Unlikely, torque is 172nm which is effing tight for something so small.

There was a similar thread a few weeks ago

where i found an alternative source of info ..a land rover manual - same engine ..but different manual

says something along the lines that if the prv is triggered by over pressure ..then it should be replaced as its no longer Guaranteed leak free

does that mean ..not leak free if you open it up ..and try to fix it

or not leak free because it now un-serviceable and the leak is a result of the triggering that renders it useless one time use..self destructs with over-pressure
