What kind of pressure / flow is there at the schrader? The rail pressure reading will be pretty meaningless until it fires up. If you are not getting a minimum 1.3 litres p/min at the schrader either the filter is blocked or the lpfp is shot.
But, the above is irrelevant if the original fault codes still present? yµ (idµ - eAµ) ψ=mψ

Update, following Robbie’s thread….
Lpfp is pumping 1.4 Ltrs in a minute.
Pump pressure at the test point in the engine bay is a steady 6 psi, while cranking.
I rigged up a fuel pump and fuel supply to feed into the test point, the engine did try to fire twice but that was it.
I still need to dig into the engine bay and check the hpfp belt, a job for the weekend.

Open a high pressure fuel line and have someone crank the engine. Fuel should continuously spurt from the open line (allow for residual!!) If there's no fuel spurting, either the HPFP is kaput or the belt has snapped since you do have a good lp feed!
One caveat though, just be careful here as the fuel if under high pressure will hurt you, and never attempt this with a running engine!yµ (idµ - eAµ) ψ=mψ
