Hi guys, I need a little direction on this one. My 2006 td4 loses power, starts ok, runs fine until I push for power then it loses power. No fault lights, scanning shows reduced high fuel pressure, if I stop the engine and restart it will run ok until I push for power. I've changed the high pressure sensor and checked the wiring to the ECU with a meter, all checked ok. If the sensor or wiring are faulty, will it always bring on the fault light?
