Suggest you look to seeing if there is 12v at the coil and is the dizzy turning with the engine being cranked... Stranger things have happened.. if al that is ok then I would be looking at the ignition relay
The things in order I would look to if there is not 12v at the coil are Relay 11, Fuse 31 and relay 19 and check the main fuse links in the aux fuse box there are three of them. othewise it could be the ignition switch itself worth looking to.
Its a process of illimination when you get this sort of problem you should check through systematicaly and mark them off when there are ok.

The plug that goes into the dizzy, check that & the wires that go into it.
Sometimes the wires break inside or the connecter is faulty.
Start from the dizzy & work through the system to find the fault.

Dave your 24V is completly different set up ignition wise to a 12V.

Well if you replace the dizzy, it is another to cross off your list but if the plug or wiring is at fault it will be the same. I thought you had already replaced the dizzy module?
