Expert:  Tan replied 2 years ago.
Ok the only things we can check are the key switch and the kill switch. This will require unplugging the main engine harness and checking for spark. Once you have the main harness unplugged locate the start relay disconnect the brown wire on the relay. Now apply 12 volts to the brown wire on the relay this will crank the engine. Now check for spark do you have spark?
