The (diesel) engine is obviously turning over and there is grey smoke coming out of the exhaust, but the car won't start. What do I need to look at and do/replace?

If you are certain that the fuel is not contaminated i.e. with petrol, then it sounds like the 'glow-plugs' may not be working. A short burst of 'Easy Start' into the engine air intake during cranking will prove this. i.e if the engine now runs then you need to have the 'Glow plugs' checked.
