  If your engine turns over but doesn't start, first, refuel if the tank is empty. If there is water in the fuel, drain and refuel. Replace old or non-recommended fuel with fresh, recommended fuel. Inspect the spark plug for fouling or defects and replace if needed. Also, check for spark at the spark plug and replace the plug if there's no spark. Ensure the battery voltage is adequate by recharging it to 12.8 VDC.
