Re: Td4 Fuel Pressure Problem... HELP!
I thought this myself, but I've fitted a replacement pump and it ran ok for a few minutes before it died again.
I used a multimeter on the cam sensor... With the ign on, the connector on top of the engine block didn't give any readings from the 3 pins, but the connector that connects into this gave the following readings with the ign on:
Red/White wire - 9.7v
Yellow wire - 9.6v
Brown wire - 0.01v
Do these readings seem ok.
More interestingly, I disconnected the green plug connected to the fuel pressure sensor and with the ign on, none of the pins gave any reading, either on the sensor side, or on the green connector. Is it safe to assume the fuel pressure sensor is knackered? Is this easy to replace? Is it a matter of using a spanner to screw it off, then screw the new one on, or will a load of diesel shoot out when I screw it off?
Also, I have a friend with a Rover 75 with the same engine as the Td4. If I was to run his car and use 3 wires to connect his fuel pressure sensor connectors to the connector on mine, would this fool the ECU into thinking the pressure in my car was that of the Rover 75 and therefore get the car to start? Would this cause any damage to the Rover 75?
