To fix a flooded diesel engine, avoid cranking the engine repeatedly, as this could cause more damage. First, turn off the ignition and wait for several minutes. This allows the excess fuel to evaporate. Remove the glow plugs or injectors to reduce compression, making it easier to crank the engine and expel the excess fuel. Crank the engine with the throttle fully open to allow maximum air flow. Once the excess fuel is cleared, reassemble the plugs or injectors, and try starting the engine again. Always ensure safety and consider consulting a professional if unsure.
