3 litre diesel Patrol engine spins but doesn't start???

Are they using a non-original key at any time. If they are using a key without the imobiliser, or they have dropped a genuine key in the dirt or dust, this can cause the vehicle to behave in the manner you've described.

Have they verified the fuel system's integrity? The easy part of this is to remove the hose from the outlet of the filter housing and prime the filter plunger. Fuel should come out of the filter outlet (the one closest to the radiator). Have they checked the filter drain bung for water? Is there any red lights on the dash (engine fault)?

Good luck to them....

Lack of compression due to hole in top of piston??

I used to get this problem with my Patrol from time to time.

When they prime the fuel filter do they get a solid resistance? When I was by myself I used to pump the plunger with my right hand and at the same time put my left hand inside and turn the motor over. As it was cranking, I would pump like XXXX. There is most probably an air lock.

[Roachie] I thought you were selling that beast of yours.

Thanks all problem has not reared it's head again.

Spoke to daughter this AM and the way it was described it was most likely the immobiliser and or dirty key.

They're out of the desert now and on the black top.

I had a similar problem with my Patrol, turned out to be a faulty injector pump sensor.

Has it got a turbo timer ??
My turbo timer wiring was bodgy after a few years of corrugated roads and it was very similar although on a different $wd so maybe have an auto elec check that when they are in a town that has one of course..
