If you're experiencing fuel-related problems, such as:
* Check Engine Light: This indicates a problem that needs diagnosis with a scan tool.
* Poor fuel economy: This could be due to several things, like a faulty sensor, air leak, or other mechanical issue.
* Engine won't start: This could be related to fuel delivery (pump, filter, etc.), but could also stem from other causes (battery, starter, etc.)
You'll need to have the vehicle diagnosed by a mechanic or use an OBD-II scanner to identify the specific issue. There's no simple button to fix underlying fuel system problems.
