The fpr doesn't always come with refurbished pumps, thought it was worth checking. The HDi needs ~280bar to fire, not much more than you'd see on an idi. If there really is that little fuel up at the rail, you will have a fault code, try getting a better reader on it.
In the meantime you could stick a multimeter on the FRPS to see what pressure it's seeing - should read about 1.3v at cranking. If that's right then you're looking at a loom or ecu/immob fault.
