  If your Polaris Offroad Vehicle engine turns over but fails to start, first refuel, then cycle the key to the ON position three times for 5 seconds each time before attempting to start. If that doesn't work, replace the clogged fuel filter, or drain the fuel system and refuel if water is present in the fuel. If the fuel is old or non-recommended, replace it with fresh, recommended fuel. Inspect the spark plugs; if they are fouled or defective, replace them. Also, inspect the plugs and verify the stop switch is on. Ensure to recharge the battery to 12.8 VDC if the voltage is low.
