Help with Diagnostics: ZD30 GU Nissan Patrol (2004 STL Auto)

[Yendor]

Re-assembled strictly in accordance with the Manual, The timing thought has crossed my mind but trying the easy ones first, a lot of work to expose drive train & check pump timing again, I will also try & run with the Catalytic converter off, will be noisey though, The thing that stumps me is when you start & put foot on throttle it is like it is not connected to engine, the revs slowly climb up and if you put the air-con on the revs drop a long way below normal idle. hate the rotten thing

Hi Don,

I don't think it is an electrical problem going by what you have said, but it won't hurt to recheck all the wiring connectors that you had apart.

Disconnect them again and inspect the terminals for damage or backed out terminals.

Also make sure you have reconnected the earth wires to the manifold on the RHS of the engine.

You could try getting Nissan to connect their computer and check operation of the sensors, but I would of expected if it was an electrical problem causing your drama that a fault code would have been recorded.

Good luck with it.

Cheers Rodney
