What are the reasons for the difficulty in starting a Chery QQ?

The reasons for the difficulty in starting a Chery QQ may include: battery damage or low charge; abnormal air-fuel mixture or unstable power supply voltage in the ignition system. Battery damage: It needs to be sent to a repair shop for testing with professional computer equipment. Another possibility is low battery charge. If the car is often driven at low speeds with headlights, air conditioning, audio, and other devices frequently turned on, the battery consumption will be higher, potentially leading to low charge. It is recommended to drive at high speeds occasionally to allow the battery to fully charge. Abnormal air-fuel mixture: In this case, the engine usually cranks normally but fails to start. This phenomenon is generally caused by a dirty throttle valve, intake valve, or idle speed control valve. If the valves are too dirty, fuel may spray onto the back and be absorbed by carbon deposits, preventing the engine from starting. Cleaning these components usually solves the problem. Unstable power supply voltage in the ignition system: In winter, the engine's starting resistance increases, including insufficient battery power, leading to inadequate voltage in the entire ignition system. Additionally, sometimes after starting, if the accelerator pedal is not continuously pressed, the car may stall immediately. This is due to a dirty combination of the throttle body and fuel injectors. Slightly increasing the throttle may help, but if the difficulty in starting persists, the car should be sent to a repair shop for a thorough cleaning.
I've driven a Chery QQ for several years, and the difficulty in starting is quite common, mostly due to insufficient or aging battery power. It's more noticeable in cold winters—when the battery is weak, turning the key just results in a few clicks without the engine starting. Another possibility is an issue with the ignition system, such as excessive carbon buildup on the spark plugs or a widened gap, preventing the ignition of the air-fuel mixture. Additionally, a malfunctioning fuel pump often causes this problem, as insufficient fuel pressure prevents gasoline from being injected. It's advisable to regularly check that the battery voltage doesn't drop below 12 volts and to change the engine oil frequently for maintenance. Never ignore the issue, as breaking down on the road can be dangerous. Last time, I almost missed an urgent matter before finally taking it in for repairs—it turned out the spark plugs needed replacement. Regular full vehicle inspections can prevent many troubles.
Many owners of repaired Chery QQ often come to the shop to consult about difficulty in starting the engine, usually due to starter failure or gear wear. You can try testing the battery yourself—use a voltmeter to measure it, and it should read above 12.6 volts to be normal. Also, if the ignition coil is leaking electricity or aging, the voltage won't transmit properly, making it hard to start. Severe carbon buildup in the throttle body can cause poor air intake and lead to issues; cleaning it might solve the problem. Don't forget to check the fuel filter—if it's clogged, fuel supply will be uneven. If you find any issues, avoid tampering with parts randomly; it's best to have a professional mechanic use a diagnostic tool to troubleshoot—safety first. As cars age, part degradation is common, and replacing them will make starting much smoother.
As a veteran driver with over 30 years of experience, I've seen countless cases of Chery QQ having starting difficulties. Common causes include loose or worn ignition switches that cause poor contact when turned. Aging wiring with current leakage in the electrical system is another factor, preventing proper power transmission. If the starter motor's coil burns out, it definitely won't fire up. Additionally, a faulty mass airflow sensor can miscalculate fuel delivery, leading to failure to start. Remember, regular maintenance of spark plugs and the battery can reduce such risks - don't wait until you're stranded on the road for emergency repairs. Starting issues may also affect idle stability; fixing them will result in smoother driving.
