Yamaha Aerox 100 will not spark?

I have a Yamaha aerox 100 which was vandalized in a theft attempt Ive had to replace the ignition system and all the locks however now that's all done it will not spark at the plug it seems no power is getting to it at all the bikes not fitted with an immobilizer and was running great before, Ive checked the ignition wiring that's all fine everything works as it should and it even cranks over with the starter button just no spark so if anyone has any idea what might be wrong i would appreciate your input thanks
