Post by sudso »

A workmates rig.

Very hard to start when it's a hot day and hard to restart when it the motors been warmed up.

Any clues? Fuel pump?

Go to the Patrol4x4 forum website. There has been plenty of discussion on it and it turns out to be a pump issue. It can be fixed with a plate and o'ring.

I have similar problems with my 2.8GU. I put in a larger battery and it seems to fire most times within 3 seconds when hot. In extreme cases it is known to pour cold water over the pump.

Cheers

Have you got a link to this article nath69. It sounds like a pretty simple fix.

The Nissan dealer in town want $2000 to fix it :shock:
