      There are several reasons why your Hisun Offroad Vehicle's engine might be hard to start. It could be due to: * No fuel flow: Inspect the fuel tank, fuel filter, electric fuel pump, and injector. Also, check the ECU with Motor Scan KF90121. If needed, replace the filter, electric fuel pump, injector, or ECU. * Water in the fuel system: Ensure the fuel tank cover is tightly closed. * Increased oil viscosity in winter: Use oils with different viscosities suitable for the ambient temperatures. * A weak battery: Clean the battery cables and terminals, and charge the battery. In cold weather (-15?), remove the battery, charge it indoors, and install it only when you're ready to use the vehicle.
