What are the reasons why the Buick Excelle suddenly cannot start?
3 Answers
Buick Excelle suddenly cannot start due to the following reasons: 1. The car battery is low on power; 2. The fuel pump is damaged, preventing fuel in the fuel tank from being supplied for combustion; 3. The engine crankshaft position sensor or camshaft position sensor is damaged; 4. The engine lacks cylinder pressure. Taking the 2020 Buick Excelle as an example, it is a compact car with the following dimensions: length 4468mm, width 1765mm, height 1469mm, wheelbase 2611mm, fuel tank capacity 40l, trunk capacity 491l, and body weight 1070kg.
I've been driving a Buick Excelle for over a decade and have encountered several sudden ignition failures. The most common cause is likely battery issues, such as an aging battery losing charge or loose/corroded terminals, especially prone in cold weather. The starter motor is another hidden danger - severe wear can cause rough starts. Additionally, ignition system components like carbon-fouled spark plugs or damaged coils can affect ignition. Fuel pump failure leading to insufficient fuel supply is another potential factor, particularly if the car has been left unused for extended periods. Electrical issues like blown fuses or false alarms from the anti-theft system may also interrupt the starting signal. When this happens, avoid repeated attempts to start the car to prevent component damage. Instead, immediately check if the battery voltage is normal or take it to a professional shop for diagnosis.
Last time my Excelle wouldn't start in the parking lot no matter what, and I found out it was due to loose battery terminals after checking. This kind of issue is quite common, especially with older cars or poor maintenance. Additionally, if you only hear clicking sounds from the starter when turning the key, that indicates a starter motor problem; if there's complete silence and no movement, it might be a blown fuse or faulty key chip. The fuel pump can easily get stuck with poor-quality gasoline, which also leads to starting failure. Recommended troubleshooting sequence from simple to complex: test electrical power by turning on lights, listen for starter sounds, check dashboard warning lights. Get it fixed promptly to avoid being stranded on your next long trip.
