why is my 2005 impala not starting?

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! No start? No problem! Focus on the ignition switch and related wiring. Ensure the ignition switch sends power to the starter when you turn the key. Check for any loose or corroded connections in the ignition circuit. If power isn't reaching the starter, the issue likely lies in the ignition system rather than the components you've inspected. I hope you can get to the bottom of this mysterious no-start! Good luck!
