230713Vehicle Owned: 1999 Nissan Patrol

Ryan Scott Gunton (Kingscote, SA)

Hi there Allan, I picked up my GU ute about 2.5 years ago after a mate of mine rolled my ’02 Triton. So far I have fitted a 2in lift, bull bar snorkel, 9500lb winch, DC2 wheels with 33in Maxxis Bighorns, 240mm Lightforce spotties and some other little things on it.

I have done a lot of driving in the centre of Australia and a heap of beach driving where I am now. I would love to go and do the Telegraph track in the Cape and have a bit of a fish up there!

I have been having a problem when my GU first starts. The problem comes about after it sits for a couple of hours and then it starts really rough and continues rough for 30-40 seconds. I have put new injectors and glow plugs into it and had my fuel pump looked at and still cannot find the problem. Have you come across this before?

Hi Ryan, yes I have come across this before. I think what you might have to do is put a fuel pressure gauge on the outlet side of the pump. I suspect it’s draining back somewhere and causing the pressure to drop off. You could check the injectors and glow plugs again to make sure they’re right, you didn’t mention if it blows smoke or what color it is.

There’s an outside chance it could be the tappets needing adjustment, but I’d still say to check the fuel pressure side of things first. Talk to a diesel specialist about installing a check-valve in the line to make sure the fuel is not running back through the line.

Hope that helps, Ryan, catch you down the track.
