      Michelle DiazSep 23, 2025
      Your Polaris Offroad Vehicle engine may require more than normal pulls to start due to poor fuel, so replace it with fresh winter fuel. It could also be that not enough fuel is getting to the engine, or that the fuel filter or tank pick-up sock is plugged, so see your dealer.

      If your Polaris snowmobile engine turns but doesn't start, first replace the spark plug(s). If it still doesn't start, check for a spark. Also, ensure the fuel valve is on and that the tank contains fuel. Ice in the fuel line, filter, or pump can also be a culprit; add isopropyl alcohol to the fuel system to address this. Poor engine compression can also cause this issue.

In this case, see your dealer. Another possibility is hydrostatic lock, where fuel may have entered the crankcase while the vehicle was standing or being transported.
