760T won't start

Just to add to this,

it cranks, there is a spark (or at least it sure felt like it) the car is on a slight angle, it sounds a bit strange when it cranks sort of loose or free.

When I first went to start it, it ran for a little bit I thought I might make it to the petrol station, well it got out the drive.

Undo the screw on the top of the timing belt cover, bend it back and have a look at the belt.

The easiest way to determine whether the timing belt has failed is to remove the oil cap on top of the valve cover and look while someone tries to start the car.

If you can see the cam turning over, the belt is not broke (although it may have slipped or jumped a few teeth).

How much fuel did you add? It's possible the pre-pump has failed, without it the system will have trouble priming if it's been run dry.

Yes, when I noticed the free kind of cranking I did suspct the cam, I've recently replaced the cam belt so I didn't think it would be broke so soon.

Anyway I checked the cam and it's still Rotating, don't know if it;s slipped but adding more petrol would probably be the quickest fix I'II try that.

I put a 5 litre tin of petrol first off.

Once our '85 765T ran dry, and the main pump failed. I've seen a couple other mentions of it when the tank runs dry... maybe the stress of running without gas can kill an old main pump? If you crank the car for a moment (returning to the "run" position) and then listen to the main pump underneath the car under the front left seat, you should hear it run for five seconds.

OK, I've had the timing cover off, all seems OK there,

I removed a spark plug and there is compression.

I have seperated a union in the fuel line and there seems to be presure,

But as Mike suggested I listened, after cranking and there seems to be no sound coming from the fuel pump,

I assume it's a fuel pump? any other way of testing to know for sure?

looks like the pin that holds the cam chain to the crank has snapped and it's not looking to good.

any chance of simple repair?

Cam belt you mean? Or is this something else? I'd be really curious how the key snapped without the belt breaking. Either way that's a non-interference engine so if you can fix the broken piece there shouldn't be any internal damage.

Are you sure it's a non-interference engine, ahh and yes cam belt!

Positive - it has been addressed at great length before. Once you get it back together it should be fine.
