The GQ Patrol was a tough old bird, but it’s old and buying one now is a gamble. You could consider a Toyota Landcruiser, but again your budget will limit you to an older vehicle and that is always a risk. You could perhaps consider fitting power steering to the XF ute.

There are only two things it can be, fuel or spark. You say it's got spark, but is it at the right time. Check the crank sensor and its connections. If it's got spark and it's happening at the right time, the problem must be on the fuel side. Have someone check the fuel pressure to make sure it does have fuel at the engine.

It’s a fairly straightforward installation without major modification to the car, and there are companies doing it. One we know does it for around $2200 drive in, drive out, and guarantee the rego authorities will accept it when you go to change the engine number.
