ENGINE STAYS RUNNING AFTER SHUT OFF AND KEY PULLED OUT

Hello, You may have an issue with your main relay. You can check it by putting your hand on the relay, and having someone turn the key to "on" with the engine off. If the relay is working, it will click as soon as the key is either inserted, or when it is turned. It should click once more when the key is turned off or removed. Let me know what you find.
