Why does your Buick century start sometimes and sometimes not?

Intermittent starting issues in a Buick Century can be caused by several factors. Common culprits include a weak battery or poor battery connections, a failing starter motor, or issues with the ignition system, such as a faulty ignition switch or spark plugs. Additionally, problems with the fuel system, such as a clogged fuel filter or malfunctioning fuel pump, could also impact starting reliability. It's important to diagnose the specific issue to ensure an effective fix.
