Broken down, again!

X 3 check along the fuel line especially as mentioned in the wheel arch area.
Fuel line is cheap enough

Checked fuel filter and re primed, didn't do anything.
Took the fuel cap off and heaps of air came out, ran better but still no good.
Check MAF all good.
Checked fault codes with paper clip and got 0505 (no fault).
Going to call racv and get a tow, hopefully to Alice. Not in a good mindset now, especially after spending around $10000 having the thing rebuilt, and sposed to be back at kings canyon Friday afternoon to start work on Saturday.
Will more or less be offloading it as soon as I can, only had it 7 months and have never even been able to get more then 2000ks without something else going wrong. Really disappointed and frustrated.

Did air definitely come out of the tank or could it have been sucking air in when you released the cap?

Heres a long shot then is the tank breather not covered in dirt from spilt fuel

Na it defiantly pushed air out. I gave it a run with the fuel caps off and was a little better but still not good. Had a look at the fuel lines and they looked all good. Spoke with racv, getting it towed to mechanic in coober pedy and will work it out from there. Will let you know when I find out what's wrong with it.
Thanks for all the help guys.

Also just for anyone who doesn't already know, Nissan are useless.
Spoke with a tech and the only advise he could give was "just get it towed", tried explaining how remote I am and how expensive it is and if he could give me any advise on anything else I could check but no "get it towed" was the only advise he gave.

Good luck in Coober Pedy and it is a shame that you have had to go through this.
Definitely sounds like an issue with fuel supply though.

I towed [rope] a VW from Pootanoo crossing to Alice.
Pootanoo is where the railway line crosses the Stuart Hwy
Sth of Mt willoughby roadhouse, was not fun at all
Get them to go over the fuel lines, one may be put on wrong
But air is getting in somehow

When it was rebuilt, was the pump refurbished / replaced? This could may well be the pump not being able to keep up ?

I expect it’ll be Bulls Garage in Coober Pedy. They’ll get you going again ...... but it may take more time than you are expecting if vehicle specific parts need replacing, so fingers crossed it’s something fixable with what they have on hand. I had to get a water pump in our bus replaced by them. They freighted a pump from a Nissan dealer in in Melbourne costing me over $700 + fitting. I later bought a new spare in Perth (albeit an aftermarket one) for $200. That little episode saw us in Coober Pedy for a week (but it was a great week!) I hope things move more quickly for you, but thought I’d prepare you for the possibility of a further wait.
