Hi guys, I really hope someone can help.

My trusty Patrol 3.0 TDI (2002) model died three weeks ago. It started as normal ran about 1km came to a roundabout, the engine died and the engine light came on. Since then it cannot be started.

It had to be towed to the Nissan workshop who then passed it onto a Bosch workshop They have just called after two weeks of scratching their heads today. They are also all out of ideas as well.


It has never had any problems in the 75,000 kms I have driven it and I am now getting a bit suspicious that they (Nissan and Bosch) are just going to change parts on a trial and error basis at my cost.

Bosch say they have removed and calibrated the diesel pump, not sure why they had to do this as it was running fine before it stopped.


To me it seems as if the fuel shut off valve has jammed shut as the way it stopped was just as if I had turned the key off.

Does anyone know what voltage has to be supplied to which wires on the injection pump to test the shutoff valve?

Also what voltages are expected on what pins from the ECU before the vehicle will start?


There is little or no information available on this subject and I am sure that one of you guys have had or seen a similar fault at sometime

Many thanks for all of your replies and suggestions in advance

What fault codes were stored? There is no stop solenoid as such, its controlled via the ecu on the pump, via the ecu in the car.

Sounds like it needs to get to someone who knows what they are doing, with the correct information.

Have you tried your other key?

For something as fatal as that there will be a code in there somewhere, even if it was NATS it would throw a code, have you actually asked them to give you any codes they extracted. If the VP44 gets a comm error that is real (mine will very rarely come up with this error but it is a false error) then the damn thing won't start until the code is cleared or the problem is fixed. If there was no smoke or other nasty's associated with the stoppage, then it sounds like a sensor has triggered something, crank angle sensor can cause some weird stuff, even a dodgy battery can, as well as bad earthing.

Sorry I can't help you with the voltages you ask about but surely the "specialists" can offer more than what they have.

Where are you located? maybe we can offer better options somewhere else.
