What are the reasons why Changan cars cannot start?
2 Answers
There are several reasons why a Changan car cannot start: 1. Battery: As the basic power source of the car, when it is low on power, the motor cannot operate normally. 2. Spark plug: The most important component in the ignition system of a gasoline engine. If the spark plug fails to ignite, the car naturally cannot start. 3. Fuel supply system: When the car cannot start, it is necessary to check whether the fuel supply system is functioning properly. If this system malfunctions, the engine oil cannot be supplied, which will also affect the normal starting of the car. 4. Motor failure: After ignition, the power will start the motor, and once the motor operates, the engine will follow. If the battery is sufficient but the motor is not operating normally, the car will also fail to start.
I've been repairing cars for over a decade, and there are several common reasons why a Changan vehicle won't start. First, a dead battery is the most frequent issue. If you often listen to music with the engine off or the battery is three to four years old, starting the car will be particularly difficult, or there may be no response at all. Second, the starter motor might be faulty—you can hear a clicking sound when turning the key, but the engine won't crank. Third, there could be a fuel system problem, such as a faulty fuel pump or a clogged filter, and the fuel pressure warning light on the dashboard might illuminate. Fourth, ignition system issues like carbon-fouled spark plugs or aging ignition coils can arise, especially on rainy days. Fifth, less common faults include the anti-theft system locking the engine or a failed crankshaft position sensor. I recommend trying a jump-start first. If that doesn't work, you'll need professional diagnostic equipment—don't force it, as it could damage the engine.
