The reason why Dongfeng Xiaokang K 17 minivan is not easy to start (50,000 km)

1. There is carbon deposit in the combustion chamber, injector and valve angle. The reason is that your gasoline combustion is not fully formed due to the long-term traffic congestion on urban roads. You can go to the 4s shop to remove the intake manifold and injector for manual cleaning, which is the most effective. If you are in trouble, you can add a special gasoline cleaner to the fuel tank every 5000 kilometers. Or you can do it together in two ways, which is better. Both methods can achieve the expected results, and the cost is roughly the same.

There is something wrong with your gasoline.

3. Check the water temperature sensor. Simply put, when the vehicle is cold-started, the engine computer board needs to receive the signal from the water temperature sensor to adjust the fuel injection amount during cold-starting. If the water temperature sensor is faulty, the engine will recognize the signal of the hot car, which makes it difficult to start the engine.
