Speedfight 3 LC does not start

Hey, I have the following problem with my Speedy (approx. 16.000km). With E-Starter it doesn’t start at all, with Kickstart until the day before yesterday almost always. Now it is no longer a motor run after a short ride to restart, completely acidifies. Today new spark plug and ignition coil with plug installed, still no sparks. Are there any problems with the CDI or also cable breaks on the handlebars? The difference between kick and e-starter made me already stubborn, now can’t go at all. If I put the CC on the ground I have no spark. Does jmd have a tip? Thanks already
