Glow plugs

[HeathGQ]

when you arrive home and turn off the truck , give the lift pump a go to see how firm it is....then next morning give the lift pump another go to see how firm it is.....if its real soft and takes a while to pump up then you may have a leak in a fuel line somewhere .
my GQ had a leak in the lift pump around the shaft so i replaced the whole thing with a CAV unit.

funny thing is mine only sucked air in and never leaked diesel out....was a bugger to find what was wrong.

Thanks SHane. That is the next thing. My little bro just got back from NZ, he's a mechanic, and he did say something similar. So I drained it, to make sure there was no water, then pumped it up. Started, but not striaght away. We'll get into it today adn see what happens.

I think I found teh problem. The lead from the relay to the plug - goes to a plugh on the inlet manifold. From here to teh first cylinder glow plug - just at this point, the conact was not good, so the plugs weren't glowing. I knew it had to be something stupid.
