What are the reasons why the Changan CS35 won't start?
3 Answers
Changan CS35 suddenly failing to start may be due to human operational reasons: dead battery, empty fuel tank, or incorrect gear position. Many common cases of failure to start are caused by improper operation, and these situations are quite prevalent. Here are the specific details: 1. Empty fuel tank: When the fuel gauge shows below the red line, the car naturally won't start. 2. Dead battery: This could be due to reasons like leaving headlights on for a long time, resulting in battery drain, or the battery's lifespan has expired. It is generally recommended to replace the battery every 2 years. Additionally, installing xenon headlights, high-power audio systems, or DVD players can also cause vehicle circuit failures. Checking for a dead battery is simple—just press the horn to find out. 3. Incorrect gear position: For automatic transmission vehicles, the gear must be in P (Park) or N (Neutral) to start. If it's in R (Reverse) or D (Drive), the car won't start. Some manual transmission vehicles also won't start if the clutch isn't depressed.
Last time when I had trouble starting my Changan CS35, I recalled several possible reasons. One is battery issues - if the battery is drained or aged, you might only hear clicking sounds when turning the key without the engine firing up. Another is the ignition system; for instance, spark plugs fouled with carbon deposits or faulty ignition coils can prevent spark generation. Fuel system problems could also be the culprit, like a failed fuel pump or clogged fuel lines preventing gasoline from reaching the engine. Additionally, check the starter motor - it's common for it to get stuck or have poor relay contact. I've even experienced blown fuses, especially during hot summer temperatures. My advice is to start with simple checks: first test the battery voltage to see if it's above 12V, then try jump-starting or replacing the battery if necessary. Remember to turn off headlights when parking and perform regular maintenance checks on these components to prevent many potential issues.
There are several reasons why the Changan CS35 won't start. First, check the power system - if the battery is drained, the car definitely won't start; insufficient voltage or corroded terminals can also affect starting. Then, for the ignition system, if the spark plugs are dirty, leaking electricity, or if there's a high-voltage coil failure, no spark will be generated to ignite the air-fuel mixture. Regarding fuel supply, the fuel pump might be broken or the fuel line clogged, leading to insufficient fuel pressure. The starter motor is also crucial - internal wear or relay failure can prevent the start signal from being transmitted. There could also be issues with the electronic control unit (ECU), like faulty sensors providing incorrect data, preventing startup. I recommend systematic troubleshooting. A simple method is to use a multimeter to measure the battery's starting voltage, observe current fluctuations during startup, and listen for sounds to identify the fault point. If you can't figure it out, take it to a professional shop for inspection. Regular maintenance can save you a lot of trouble.
