Good result.
He is a smart cookie Tony.
He'll keep going until he figures it out.
I had a similar problem where it would just stall and the only way to get it to start again was to prime the fuel.
I took it to Nissan nothing was fixed took it to another Nissan dealer and they remapped the fuel pump to suit 4x4 driving. It has never stalled since. (on it own anyway)
Maybe try another dealer. Maybe try getting it remapped also.
Hey guys,
So im glad to finally give you some good news. After writing a letter to nissan australia themselves i finally started to get somewhere. I sent the letter off probably 5 weeks ago now and heard back from nissan about 2 weeks after. They have pretty much admitted that they can not find the problem and are going to replace my Navara with a brand new one. I originally owned a black one, and due to the popularity of that colour it was not available till December this year. I have already been driving the hire car for over 10 weeks and Im pretty sick of it. So I have gone with silver. I got a call today to say it had arrived at the dealership and well be getting the accessories put on this week. Should be ready friday. YAY!
