If your symptoms sounds like an ignition problem then Coils and igniters usually cannot be repaired. If you like to repair the coil then I recommend duct taping the coil or soak the coil in epoxy or epoxsy the crack formed in the coil and let it cure. An ignition switch can be repaired in some cases, but most often not.
