What are the reasons why the Changan CS75 won't start?

The reasons why the Changan CS75 won't start may include: rust or leakage in the battery, or moisture in the engine spark plugs on rainy days. Below are the maintenance methods: 1. Check whether the battery fluid in the battery is sufficient. If the liquid level is between the upper and lower two lines, it is considered appropriate. Also, check the liquid level difference in each slot. If the liquid level is insufficient, unscrew the cover on the battery and pour in distilled water to replenish the liquid level. 2. Check the battery terminals and use an iron brush to remove accumulated dirt on the terminals. If the terminal clamps are severely soiled, use sandpaper to rub along the inner wall to remove the dirt. 3. If the spark plugs are damp, remove them and use a lighter to bake them to quickly evaporate the moisture on them.
I've repaired quite a few Changan CS75 vehicles before, and the most common issue causing failure to start is battery-related problems. Either the battery has aged or is depleted, possibly due to leaving headlights on or long-term disuse causing power leakage, especially prone in winter. Next is starting system failure, such as a burnt starter or faulty relay, with symptoms being only a clicking sound when turning the key but the engine doesn't crank. Ignition system issues like spark plug carbon buildup or weak ignition coils can also cause difficulty in starting. Fuel system-wise, a broken fuel pump or clogged fuel line cutting off fuel supply will prevent the engine from starting. A failed crankshaft position sensor means the ECU doesn't receive signals and won't allow startup. Occasionally, the electronic control unit (ECU) might malfunction and cause issues too. When troubleshooting, first try jump-starting; if that doesn't work, check the fuses. Regular maintenance is key—inspecting the battery and fuel system every six months can prevent problems before they occur. Don't wait until you're stranded on the road to panic.
I've been driving a Changan CS75 for several years. Once during a trip, the car suddenly wouldn't start, which was quite a scare. The possible reason was insufficient battery in the remote key, and replacing the battery solved the issue. Battery aging is a significant problem, especially in cold weather when it's prone to failure—checking the voltage can tell. If there's a cranking sound but the engine doesn't start, it's likely a starter or relay issue. Fuel-wise, an empty tank shown on the gauge or a faulty fuel pump are common culprits, so remember to check if the fuel line is clear. Sensor issues like a faulty idle control valve can also have an impact. As a temporary solution, carrying an emergency jump starter is wise. Always turn off all electrical devices before shutting down the engine to save power—developing good habits can save a lot of trouble. Regular maintenance can greatly reduce such embarrassing situations.
Speaking of the Changan CS75's failure to start, I've analyzed quite a few cases. The main causes are often a depleted battery or one that's reached the end of its lifespan—jump-starting can provide a temporary fix. When the starter motor fails, the engine makes noise but doesn't turn over, and a damaged relay can also be a trigger. A faulty fuel pump can cut off fuel supply, or a clogged filter may starve the engine of fuel during ignition. A failed crankshaft sensor can mislead the computer into preventing startup, and humid conditions can exacerbate the issue. It's advisable to keep some tools in the car for self-inspection, like listening to the startup sound for clues, and ensuring the key is firmly inserted. Regularly monitor the battery's condition and avoid unauthorized circuit modifications to stay safe.
