Why is my Hisun 750UTV Offroad Vehicle engine difficult to start?

  If your Hisun Offroad Vehicle engine is difficult to start or won't start, there could be several reasons. It might be due to no fuel flow, so check the fuel tank, fuel filter, electric fuel pump, and injector. Also, inspect the ECU. If necessary, replace the filter, electric fuel pump, injector, or ECU. Another cause could be water in the fuel system, so ensure the fuel tank cover is tight. In winter, increased oil viscosity can slow the engine revolution, so use oils with different viscosities suitable for ambient temperatures. Lastly, a weak battery can prevent the engine from turning over quickly enough. Clean the battery cables and terminals, and charge the battery. In cold weather, remove the battery, charge it indoors, and install it only when you're ready to use the vehicle.

  If your Hisun Offroad Vehicle engine overheats, it could be due to several reasons. The engine might be overloaded, so shift to a lower gear or reduce the load. Check the coolant level and fill the cooling system to the correct level, inspecting the radiator and hoses for leaks. Also, check if the motor-driven fan is turning and ensure the fuse is not blown, inspecting the electric system. Remove any trash from the radiator core or grille screens. Finally, if the coolant flow route is corroded, flush the cooling system.

  If your Hisun Offroad Vehicle engine power is insufficient, it could be due to several reasons. Ensure you have sufficient fuel by checking the fuel system. A clogged injector can also cause this issue, so clean or replace it. If the crankshaft position sensor is bad, replace it. Also, check if the air cleaner is clogged and clean or replace it. A dirty or fouled spark plug can also lead to insufficient power, so clean or replace the spark plug. Lastly, a bad ignition coil can be the culprit, so replace the ignition coil if necessary.

Why is there transmission noise in my Hisun 750UTV Offroad Vehicle?
- R
  Ronald CarterAug 28, 2025
  If you experience transmission noise in your Hisun Offroad Vehicle, it could be due to a big matching clearance for the inner and outside gears of the transmission shaft, a big clearance of transmission gears, or a non-good connection of the gear end face. In any of these cases, replace the gears.

  If your Hisun Offroad Vehicle has less vehicle power, check if the parking brake is engaged and loosen the lay-up rod. If there is non-full uncoupling for the disc brake, contact the distributor. Also, if there is CVT transmission sliding, remove the grease for the clutch and replace the CVT transmission belt and the clutch.

Why is there non agility for gearshift in my Hisun 750UTV Offroad Vehicle?
- J
  Joseph WilliamsSep 4, 2025
  For non agility for gearshift in your Hisun Offroad Vehicle, it may be due to high idling speed of engine, high rotary speed for clutch connection, non good adjust for gearshift stay wire, or gear abrasion. Replace the throttle cable, throttle petal, or the throttle if the idling speed is too high. Replace the junior clutch spring or the primary clutch if the rotary speed for clutch connection is too high. If the gearshift stay wire is not adjusted well, put the gearshift rod and arm into the 'N' position, adjust the stay wire and bolt, and lock tightly. Replace the gears if there is gear abrasion.
