You should make changing the fuel filter part of your annual maintenance on your Pontiac Sunfire. This will help prevent problems caused by a dirty or clogged fuel filter. A bad fuel filter can diminish the power of your engine, can cause it to stall on a regular basis and can even be the reason it will not start. The process to change a Sunfire fuel filter is easy. However, it varies slightly from the typical fuel filter change on other cars.
Tools Used: Tools, Flat-head screwdriver, Glass container, Adjustable wrench, Replacement fuel filter, Yellow Teflon tape (optional)
Change Fuel Filter
Park your Sunfire on a level surface. Open the gas filler cap and pump the gas pedal three or four times. Doing this will remove pressure from the fuel lines, and less gas will leak out of the lines when you disconnect them.
