So you've got fuel?

Got spark?

Got rotation on turn over?

What were the plugs soaked with? fuel or possibly water?

If not fuel then a head gasket probably gone.

yes ive got fuel, spark, and rotation on turnover, the plugs where soaked with fuel which evaporated after about 10 seconds but replaced them anyway, would the crankshaft sensor stop it from starting like this ?

I'm pretty sure this would result in a blowback if the spark was retarded or advanced.

Pull the plugs from all cylinders and crank the engine. (remove plugs from HT to avoid flashing up of fuel vapour)

Get someone to put a finger in each plug port in turn and see if there's any suction or blow on each one.

Maybe you could try hotter burning plugs too.

I was looking through an old ford TIS disc i have and a possible cause of wet plugs apparently can be underfuelling strange as it sounds.

May be worth checking fuel flow and fuel filter etc.
