More help please.
First a brief diary of event so far.
Aux belt tensioner failed and took out the belt. These items were replaced. (the engine did boil up but only lost 2 pints of coolant)
Engine started fine but cut when it got to temp. Leave for 5 mins restart ok then cut and so on.
Suspect crank sensor now replaced.
Engine started ran for 1 min or so and cutout and now will not fire at all.
Paperclip test shows 73 mass air sensor voltage low.
I've checked all the pipework around area where I was working when replacing the belt and can fine nothing obvious. All pipes and rubber conectors appear ok and there is nothing I can see hanging. All the plugs are conected. All the larger pipe clips are tight.
Any ideas would be appreciated.

Thanks Pete

V6 will start with a MAF disconnected, any other codes?

Also, not sure why a snapped auxbelt would cause you to loose coolant? It will stop the water pump turning, but it should not create a leak.

Genuine?

It will if you ignore it for long enough. No water pump = no coolant through the radiator = no heat transfer = gets very hot = it boils over & spews coolant through the relief valve in the header tank = loss of coolant

Good point, did not think of that. But loosing 2 pints is going some!

The coolant loss was thro the header tank filler cap and yes genuine sensor.

When it actually runs, does it run on all 6?

I sent you a PM yesterday...

Fired up second or third piston up and ran sweet as a nut for around a minute then just cut out and died.
