Help fuel supply question suspect regulator?

Hi I need to once again as you all for your advice.

The car broke down the other day with the AA recovery person advising it was a fuel pump issue. Sure enough I had power to the pump terminals and I could not hear the pump prime, so order and fitted a new pump and still the car will not start.

Whats odd is that under the bonnet I have zero fuel pressure at the Schraider valve, and the pump definitely primes then stops. When I slacken the lock nut off on what I think is the return on the fuel rail I have zero pressure or fuel, however there is plenty of pressure going into the fuel pressure regulator on what I suspect is the supply from the pump/filter.

Please can anyone advise what have I missed or what can I try?

Regards

Nigel
