If the light *isn't* going off after refueling, there are a few possibilities:
* Low fuel level sensor issue: The sensor in your fuel tank might be faulty and not accurately reporting the fuel level. This requires professional diagnosis and likely replacement of the sensor.
* Instrument cluster problem: Rarely, there could be a problem with the instrument cluster itself, preventing it from accurately displaying the fuel level and turning off the light. This also needs professional attention.
* Faulty wiring: A break or short in the wiring between the fuel level sensor and the instrument cluster could prevent the signal from reaching the gauge. This requires a qualified mechanic to trace and repair the wiring.
* You haven't filled the tank enough: Make absolutely sure you've filled the tank completely. Sometimes it takes a truly full tank to reset the light.
In short: If you've filled the tank and the light remains on, don't try to force a reset. Take your Ford Ranger to a qualified mechanic for diagnosis and repair. Attempting to troubleshoot electrical issues yourself could be dangerous and potentially damage your vehicle further.
