What to do if the engine does not start on my Hyundai Excavators?

  Maurice CaseAug 3, 2025
  If the engine of your Hyundai Excavators does not start when the starting motor is turned over, you should first add fuel. If that doesn't resolve the issue, check for and repair any air leaks in the fuel system. Also, inspect the injection pump and nozzle, check the valve clearance, and verify the engine compression pressure. In cold weather, ensure the fuel warmer system is functioning correctly.
