Engine Flooding

Engine flooding is a problem that is common in carburetor engines but very rare on fuel-injected engines. The fuel-injected engine might experience this problem under extreme conditions like low temperatures. It can happen when the engine stays for a very long time without running. A dormant engine becomes cold. If it ignites, the fuel and air will enter the engine as usual. If it goes off, it may strain to restart. At this point, your engine will be experiencing flooding.

Engine flooding occurs when excess fuel flows into the engine and soaks the spark plugs of your Daihatsu Hijet. Spark plugs play the role of producing ignition that initiates combustion in the cylinders. When plugs are wet with fuel, they will not be able to produce a spark in the engine. Engine flooding is not common with diesel engines because they do not use spark plugs to start.

Troubleshooting Daihatsu Hijet Mini Truck Flooding

Before troubleshooting Daihatsu Hijet, consider safety measures first. Ensure all doors and windows close to your vehicle are closed. If you are performing the procedure in the garage, the garage doors should be open, and there should be proper air circulation. Doing this is necessary because the exhaust pipe will produce a lot of smoke if the engine ignites.

Perform the following procedure to troubleshoot your flooding engine.

  1. Expose the engine for around 20 to 30 minutes. Exposing the engine will let the excess fuel evaporate. After seeing all the fuel evaporate, it may fail to start because the spark plugs might still be wet with the fuel. Check the spark plugs to ensure they are also free from excess fuel.
  2. Step on the gas pedal to the floor, and do not release your legs. While your legs are on the gas pedals, start the engine sequentially. Doing this will open the throttle, and air will flow into the engine. The air will mix with the engine’s excess fuel and bring an equilibrium, causing an ignition. After your engine has ignited, let it run for a while before engaging the gears.


Troubleshooting a flooding Daihatsu Hijet engine is not a difficult task. Suppose your engine is prone to flooding and has served you for years. Just rush to the showroom and buy a new mini truck. If it refuses to start, call a mechanic to check it. The above procedure is a home-based remedy to help you if you experience a flooding engine.
