GQ no go sometimes!!!!!!!!!!!!!!!!!!

Hi

Check out thr fuel system, and I mean from the back to the front. I had the same symptons with a GU, but it was only the filter. I have had problems with a petrol vechicle where a screen filter in the tank would block up when driving, only on good open flat roads, when stoping and starting or on the rough stuff the movement in the tank would keep it free ofbleepand forward motion was achieved.
Regards

The dealer cleaned the lines and replaced the filter as a first step. The problems seems to be very intermittent so I assume the fuel lines are OK otherwise the problem would be there most if not all of the time. The problem has been going on since early December and I have used about three tank fulls in that time so fuel quality is not an issue.

Sad when the dealer cant fix it!!!!

do these things have electronic throttle control?
the new hilux has. it is a servo controling the electronic fuel injection
the servo could be faulty? explans the tapping on the throttle then it works.

I agree with Greg ... it's likely to be the electronic throttle. Either the servo at the the throttle body end, or maybe the sender at the accelerator pedal.

Hi,

Just wondering..... I have a 2000 GU which has a very imtermittant problem (ie has not occured in over 5 weeks but prior to that I had it happen 5 times in one trip to Central Coast, and I was able to reproduce it quite regulary going up a specific hill near home first thing when the car was started at any time of day, but there were other times where it was fine) (I've only noticed it in 3rd and 5th gears) and when engine revs are about 2500 - 3000 I get this sudden loss of power....its like the waste gate on the turbo opens up and the engine revs slowly decrese, taking the foot off the accelerator and pushing it down again resets it and engine revs pick up and I accelerate up the hill or on the flat

West End Diesel have looked at it and cannot reproduce it, they said if the waste gate opens this would casue an error code in the ECU which they found none (error codes)

I'm guessing here but you could have a faulty injector.....as the GU's are direct injection they have a two stage injector ie they require something like 160psi for the first stage and 320psi for the second (don't quote me on that). Why I do not know I only say this as West End Diesel tested my injectors and said I had one which was border line on the second stage and explained it to me in their lingo but if they are faulty it can lead to lack of power and maybe it is good somedays and sticks a little on other days but @ $500 per injector and you don't replace one you replace the lot...$2000 buck I don't have at the moment.

This is great feedback, thank you. I went up to New Norcia on the weekend with a tandem trailer and light load and empty trailer back. Road was quite rough and the Patrol performed fautlessly. Went crawling around the feedlot in the heat, dust and rocks all OK so the fault is very intermittent. It just happens when it wants too and no amount of "tricks" will invoke it. The Nissan Dealer has taken it on and we are now waiting for a Nissan Australia response to a heap of diagnostics. I will post the outcome as it seems to have alot of people perplexed including me.
