Check the function of the neutral switch and the ignition switch. Sometimes, the neutral switch might be misaligned or faulty, preventing the engine from starting. You can test the neutral switch with a multimeter to make sure it’s working correctly.

Also, inspect the ignition switch itself. If it’s worn out or has internal damage, it might not be sending the proper signal to the starter relay. Sometimes jiggling the key in the ignition can give you a hint if it’s faulty. If you suspect it’s the ignition switch, replacing it could resolve the issue.
