Thread: New Territory engine in D3, Engine System Fault, please help

AWESOME NEWS
ENJOY

Great stuff . Look forward to seeing some reports of it in action.

Cheers Ean

So the 4.95V would have been 4.95V analogue for the FT sensor rather than a pwm signal. Unfortunately if you had been able to verify the signal type then perhaps you would have found the fault earlier and saved some hair! Next time?

I would be well and truly up for the engine swap,easy peasy.
But a miss connected connection like this would kill me too.The electonic signals are way beyond me.

Once bodging together a dodgy connection, she starts immediately and runs smoothly.

I forgot also to advise.... take lots of pics with your phone before and during removal, to prevent this very simple mistake but ohhh sooo VERY frustrating.... great you found it and have the beast running.

I was updating my reading to see how far you had got, Graeme was providing plenty of info, directions and asking all the right questions etc, so i wasnt going to input anymore...

I was getting the sinking feeling when you had got to the point of mentioning the fuel solenoid (PCV) being from the territory. So the High Pressure Fuel Pump is the Territory pump correct??
(for others: this is on top at the back of the engine and is belt driven from one of the camshafts).

and just a passing after the fact comment...
On a common rail diesel engine, the high pressure side of the fuel system (outlet from the high pressure pump, the "common" rail/s, the injector pipes) typically while running on idle will be around 3000psi - 5000psi (yes thousand) and upto round 35,000psi under full load, its not good practice to "crack and bleed" that side of the fuel system, and there is no need to do this, pressure comes up during cranking and drops off very quickly on shut off, the fuel regulator on the rail will "bleed" up that part as needed.

Well, at least your early thought was correct - you were sure it was going to be something simple.

Simple things can be hard to find though - great news it's a goer.

Yes, the new motor has Territory HPFP, injectors, EGRs etc. Plan to block the EGR's shortly, as soon as the money factor allows. Was hoping to have taken more photos and a more methodical approach, but after 3.5 months, I only cared about getting it running again...

Gday Winaje,


By chance did you notice if the viscous fan on the Territory engine is the same as the D3 .
