No 2. Bad spark plug

A spark plug in your car ignites compressed fuels such as aerosol, gasoline, ethanol, and liquefied petroleum gas by means of an electric spark. If your car doesn’t start then it’s a pretty good guess that the spark plug or plugs in your car have gone wrong.

No 1. Plugged fuel filter

A clogged fuel filter can simply prevent fuel from flowing into your vehicle’s engine, and that can prevent engine combustion. Ironically, this fuel filter is necessary to prevent dirt and other debris from clogging your vehicle’s fuel delivery system, a condition that severely disrupts engine performance.
