What are the reasons for the Chery QQ having difficulty starting?
2 Answers
Chery QQ having difficulty starting may be related to battery damage, incorrect air-fuel mixture, or unstable power supply to the ignition system. Battery damage: It needs to be sent to a repair shop for testing with professional computer equipment. Another possibility is battery depletion. If you often drive at low speeds in the city with headlights, air conditioning, audio, and other devices frequently turned on, the battery consumption will be relatively high, potentially leading to depletion. It is recommended to drive on the highway to fully charge the battery. Incorrect air-fuel mixture: This is also the most common and typical reason. In this case, the engine usually cranks normally but fails to start. This phenomenon generally occurs when the throttle valve, intake valve, or idle speed motor is too dirty. If the valves are too dirty, the fuel will spray onto the back and be absorbed by carbon deposits, preventing the car from starting. Usually, cleaning them can solve the problem. Unstable power supply voltage to the ignition system: In winter, the engine's starting resistance is greater, including insufficient battery power, leading to inadequate voltage in the entire ignition system. Additionally, many car owners report that after starting, if they do not continue to press the accelerator, the car stalls immediately. This is because the motor and fuel injector combination is too dirty. You can slightly increase the throttle, but if that doesn't work, you may have to send it to a repair shop for a thorough cleaning.
I think there could be several reasons for the difficulty in starting a Chery QQ. First, the most common issue is related to the battery, such as aging or insufficient charge, especially in cold winter weather when battery performance declines. I've driven similar small cars and experienced difficulty starting a few times, only to find out later that the battery, after four or five years of use, needed replacement. Second, the ignition system might also be faulty; for example, excessive carbon buildup on the spark plugs or a damaged ignition coil can affect ignition efficiency. Other issues like the fuel supply system—if the fuel pump isn't delivering enough fuel or the injectors are clogged—can also prevent the engine from starting. Additionally, checking sensors, such as a faulty crankshaft position sensor, which can interfere with ignition timing, is advisable. In summary, the Chery QQ is a small-displacement vehicle, and its component quality might not match that of higher-end cars. Neglecting regular maintenance can easily lead to problems. I recommend first measuring the battery voltage, and if that doesn't help, take it to a repair shop for a comprehensive check to avoid travel disruptions.
