3.9 v8 disco not starting

hey everyone i've got a 3.9 disco i was driving along to day and it just died on me i cant work out what it is its had new leads plugs roter arm dizy cap and dizy and i put a coil on it to day but still no luck the engine just turns over but theres no spark could it be a faulty alarm? if anyone can help it would be a big help because im on the verge of pulling my hair out lol many thanks guys

Hi have you looked at the dizzy itself? i have heard about a few problems with the air gap inside the distributor! i could be right or maybe im just talking ****e but its worth a look!

also check the pick-up wires on the side of the dizzy aint broken.

It was ok til you changed the coil today?
That's where I'd look first
