hello Brian
I have been looking at the wiring diagrams and the fuel pressure regulator gets it power from the engine fuse box F1 from there it goes to connector c0450 c0160-3 then from there it goes to the c1667(RW) connector on the pump from there (NU) it goes to the ecu so if this regulator isn't having power then there would be no high pressure reading and so the ecu would not then send a signal to the injectors what do you say I shall have a look tomorrow
