Hi TDV6 2.7 diesel. I set out on this project to see if it would be possible for a human to understand the operation of the high pressure fuel pump . I identified that the supply to the two regulating valves on the HPFP were both fed from a common supply from the ECU (engine control module)...

Since then I have wired in low watts lights into the valves so can see , When starter activates both Pressure and Volume valves get only 2.6 v and i cannot see this being enough and consequently the cranking does not build rail pressure(gauge display) I s the ECU waiting a signal to release...

Thank you tyregeezer, to get me started I soldered in insulated wire to bridge the breaks. What a bad design all those copper bar conductors and water ingress or condensation - not good. Bonus is my EPB after much work was still showing yellow on the dash and now all clear. Let me see if you...

Finally bottomed the prob No comms reported various module and to ECU Pulled out wiring harness - there are two components. One goes to the auto trans plug and the other goes to the rear transmission case plugs. There is wide misconception - the TCU is inside the auto transmission by removing...

Many thanks guys - loads to go on . C2603( under ABS pipes) earth stud has no wires on it and no obvious loose connector nearby. Should the transmission casing have an earth strap to it that could be missing ? On this selector its a solenoid and that clicks but not so operating brake pedal so...

Thanks for that but no change . I get park brake switch on and off, but its the selector that is stuck in Park and the knob push in button is locked. If could understand the Land Rover wiring diagram but it seems to me I am missing fine detail like where is the latching solenpoid earth and what...

D3 96 DV6 HSE auto diesel restoration. , Park brake drums serviced and set up in accordance with LR manual- works fine on the electric Pbrake switch works well both on and off. But the selector latching solenoid is not getting power(checked solenoid its ok on 12v) Fault on dash is auto park...

Thanks for that but it is wired up to the car harness so i am using the car ecm etc.

Hi- working on it. So when you say pin number where are these is it in the ecu or somewhere else?

for all the info - lots to do yet.

Thanks

Hi I am Peter ex Cummins Done a rebuild V6 2,7 diesel-out of body. Suprisingly a few mountains to climb. 1 Hi pressure fuel pump solenoid valves receive + supply but earth returns to ECU seem dysfunctional. 2 Squirt to injectors timing out. 3 Autotrans module not communicating 4 handbrake fault...
