What to do when the Buick GL8 has fuel and power but won't start?

[VonPatrick]

Buick GL8 having fuel and power but failing to start is mainly related to the battery or antifreeze. The specific solutions are as follows: Check if the battery has power: It may be due to a drained battery caused by leaving the headlights on for a long time or the battery reaching the end of its lifespan. Generally, it is 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. Add antifreeze: Some car owners add water or low-quality antifreeze, which can lead to the entire cooling system freezing in extremely cold winter conditions. This can cause the engine to crack, preventing the water pump from functioning and making the car unable to start, while also damaging other engine components.
