The reasons why the Buick Excelle has power but won't start are as follows: 1. Battery depletion: Battery depletion doesn't mean the battery is completely dead, but rather that the battery voltage is insufficient to start the car. In this case, you need to jump-start the car or replace the battery. 2. Spark plug damage: Damaged spark plugs in the engine are one of the reasons why the car won't start, as spark plugs are necessary to ignite the gasoline in the cylinders and get the engine running. 3. Distributor circuit failure: The main circuit for starting is the distributor. If the distributor is damaged, it may also prevent ignition. 4. Starter damage: The starter is responsible for turning the engine during ignition. If the starter is damaged, the car won't start.
I've been driving a Buick Excelle for many years and encountered this issue last summer. The battery clearly had power, but the car wouldn't respond when turning the key. At first, I thought it was a starter problem, but later found out it was a faulty starter relay. This relay controls the ignition current and tends to age, leading to no response. It could also be due to worn carbon brushes or loose wiring connections. Check the fuse box in the front of the car; sometimes replacing the relevant fuse can solve the problem. Additionally, don't forget that the engine control module might malfunction—it manages the entire starting system, and if the anti-theft device is locked, it can also prevent starting. I suggest first checking the fuses and relays yourself. If that doesn't work, take it to a 4S shop and let the technicians diagnose it with professional tools—it's more worry-free. Don't delay too long, as it could affect driving safety. This issue is quite common, so don't worry.
