For those in the future chasing down an outcome - for me the D22 was sold to a wrecker for $1400. It was out of rego and my thinking was was the cost of replacing the pump and registering the car was close to or equalled the resale value of the car which I figured around $8k (or $6.4 if you...

The way my diesel mechanic relative explained to me was the pump failed at temperature due to the diesel 'thinning" as it heated and the fine tolerance the pump operated at meant it failed to achieve compression - which it could achieve when cold. Otherwise I have no idea. Of course mine does...

back from some time away. My fault codes do no include the pump either. Went to the local wrecker and they will sell me a pump for $1.000 with no guarantee. The D22 it is from had the engine stripped down by a local workshop for not starting. According to the wrecker they did not find the...

Eric - sadly I have to agree. Two of the three mechanics that have looked at my Navara have said that the pump is the most likely culprit. I have checked after the weekend and (with the line detached to the injectors) fuel is coming out of the injector outlet (and from the pump back to the tank)...

Yes it does have such a valve which appears to be working on mine, Actuated I guess as you say by the ECU through a relay I think. Can see it working as the engine cranks. Closes and then opens when cranking stops. No I have not unplugged the NPS - will give that a try that next week. Thanks for...

In my case, perhaps a little further into the abyss, I can only agree (and hope) with Slow Learner that this is electrical. I have blocked of the EGR with no benefit. I have tried the leaving the heat switch on. I have not found another temperature sensor to disable or replace. The significant...

I have been dealing with this problem for six months with my ZD30 Navara. Initially the same issue (not starting/stalling when hot) and eventually not starting at all. Except for once a week or two ago when for no apparent reason it ran all day. Next day no start. Had three mechanics look at it...
