How to start a Doosan G100-SIIIA Portable Generator if it cranks but won't start?
- B
  Brian NguyenAug 20, 2025
  If your Doosan Portable Generator's engine cranks but doesn't start, there might be several reasons. First, ensure you're following the correct starting procedure. Check if there's fuel in the tank and that the manual shut-off valve is open. Inspect for any exhaust restrictions and correct them. The fuel filter might be plugged or full of water, so replace it or drain the water. Also, verify fuel flow at the supply pump or bleed the fuel system. If these steps don't work, the injection pump or nozzles could be faulty, requiring professional repair or replacement.

  If your Doosan Portable Generator engine overheats, the first thing to do is reduce the load on the engine. Check the coolant level and fill the radiator to the proper level, inspecting for leaks. Also, check the engine oil level and add oil if required. Other potential causes include a faulty radiator cap (have it checked), a stretched or defective belt (check and replace if needed), a cooling system that needs flushing, a defective thermostat (remove and check it), a defective temperature gauge or sender (check water temperature with a thermometer and replace if necessary), or using an incorrect grade of fuel (use the correct grade).

  If your Doosan Portable Generator is hard to start, begin by removing any load from the engine. Review the starting procedure to ensure it is correct. Check the fuel tank to make sure it's not empty. If there's air in the fuel line, bleed it. For cold weather, use cold weather starting aids. Ensure you are using oil of proper viscosity. Consult your fuel supplier to ensure you're using the correct type of fuel for the operating conditions. If there's water, dirt, or air in the fuel system, drain, flush, fill, and bleed the system. Replace the fuel filter if it's clogged. Finally, turn the key switch to ”OFF” then to ”ON” to reset the injection pump shut-off.
