Can anyone help me out with my Ignition problem?

[Chris!]

I have a Mk1 Cortina GT 1500 Pre Xflow which someone has converted to negative earth and fitted an electronic ignition. It was working perfect yesterday but when I tried to start it today it didn't want to go, I have no spark what so ever. I'm getting power to the coil so I can't work out the problem, the dizzy seems fine

Thanks

P.s it's not my blue car, that's running perfect on points

[ox]
