which fuel pipe did you check? the one that is jubileed to the regulator? if so, that is the return and will not have pressure. you need to check the one that goes to the fuel rail at the other end to the reg. but you should easily hear if the fuel pump runs or not.

with the ignition switched on, unpug and plug in the phase sensor (inside the dizzy) and the pump should run (or at least it does on mine with L6 ecu)
