* Check Engine Light: If your Check Engine light is on, you need to have the codes read using an OBD-I scanner (not a simple button reset). The codes will tell you what's wrong.
* Fuel pump issues: A faulty fuel pump won't be fixed by a button. You'll likely need to replace the pump or address other fuel system problems.
* Fuel gauge issues: A faulty fuel gauge won't be reset with a button. You might need to check the fuel gauge sending unit or wiring.
* Other fuel-related problems: Most fuel system issues require diagnosing and repairing a specific component, not a simple button press.
If you're experiencing a fuel-related problem, describe the symptom, and I might be able to give you more specific advice.
