If your 1995 Ford Ranger's low fuel light is on, you should:
* Refuel your vehicle as soon as possible. This is the most important action. Running out of gas can lead to problems starting your vehicle and potentially damage the fuel pump.
* Check your fuel gauge. Does the gauge needle confirm the low fuel light? If the gauge is wildly inaccurate compared to the light, you might have a faulty fuel gauge sender unit (located in the fuel tank).
* Consider the accuracy of the fuel gauge/sensor. Fuel gauges aren't always perfectly precise. You might have slightly more fuel than you think.
If the problem persists even after refueling:
* Check for electrical issues: A faulty connection in the fuel gauge wiring, a blown fuse, or a problem with the fuel level sensor itself could be causing the light to stay on even with a full tank. This would require a mechanic or more in-depth troubleshooting.
In summary, the low fuel light is a warning. Refuel your vehicle, but if the light remains on after refueling, a more serious issue might exist, requiring a check of the fuel gauge system by a qualified mechanic.
