* Check Engine Light: You can't reset the Check Engine Light with a button. The light indicates a diagnostic trouble code (DTC) stored in the computer. To clear the light, you need to fix the underlying problem and then the light will usually clear itself after several successful drive cycles, or use an OBD-II scanner to clear the code (though this doesn't fix the problem, only the light).
* Fuel Gauge: If your fuel gauge is inaccurate, there's no reset. The issue is likely with the gauge itself, the sending unit in the fuel tank, or wiring.
* Fuel pump relay/system issues: There is no "fuel reset" button for a malfunctioning fuel pump, fuel injector, or other components of the fuel system. Troubleshooting these requires checking fuses, relays, and other components.
If you're having a fuel-related problem with your 1993 F-150, you'll need to diagnose the specific issue rather than looking for a reset button. A mechanic or an OBD-II code reader can help pinpoint the problem.
