What are the reasons for the Buick Excelle having power but no response when starting?
2 Answers
Buick Excelle having power but no response when starting may be due to loose connections between the battery and the terminals, or it could be a damaged starter. Below is an introduction to the issue of no response when starting: 1. The starter on a car generally does not experience many faults because the starter only works for a few seconds each time it is used, and the total working time of this component in a year is only a few hours. 2. The battery is a component that is more prone to faults. The battery is responsible for starting the engine. When starting the engine, the starter needs to work, the ignition system needs to work, and the fuel pump needs to work, all of which rely on electricity. There are two terminals on the battery, and there is a component on the wire that connects to the terminals, allowing the battery to supply power to the car. This component may become loose, preventing the battery from supplying power to the entire vehicle.
I had a similar experience with my Buick Excelle recently – the battery had power but the car just wouldn't start, which was incredibly frustrating. The mechanic later explained several possible causes: The most troublesome issue could be a starter motor failure, especially problems with the solenoid switch or worn carbon brushes. It might sound like a tractor but still fail to crank. Another possibility is a malfunctioning gear position switch – even when in 'P' park, the computer might mistakenly think it's in another gear, requiring you to shift repeatedly to reset it. A locked steering wheel can also interfere; remember to jiggle the wheel slightly while turning the key. Additionally, dirt on the key recognition area or an erratic anti-theft system might falsely identify you as a thief despite having the key. The most deceptive issue is corroded or loose battery terminals – they may appear functional but fail to deliver current to the starter. For older vehicles, burnt contacts inside the ignition switch could be the culprit, which was ultimately solved in my case by replacing the switch.
