    Yep I can see it, two screws accessible the third not so, hence the removal of the inlet.

    The problem is I cannot hear the in tank fuel pump working, I've got a new one but methinks far less effort to fit that then this valve.

    Have checked all fuses and the relays but would appreciate if you can remember if you could hear your pump working when you had the fault? Or does the valve actually tell the in-tank fuel pump when to run?

    Well I've changed the valve on the front of the pump, along with the pressure sensor and the fuel pressure regulator and mine still won't start.

    It is reading 745 across all 6

    So potentially either

    a) A fault with the cam follower in the pump, or
    b) A faulty fuel filter (although I don't think this would manifest with such a high pressure
