Do you have a pump prime when you first switch on first thing of the day ?
If yes you know you are getting a cps signal, if not look at this, I think it is possible to accidentally mix up the cps and dizzy terminal connectors, especially if connector on cps has been changed to black, can't remember if both side were white or just the connector side and not the loom side.
I would just go through everything and recheck bound to be something daft and silly that you will slap yourself for when you see it!!
