The problem with the gas gauge is due to a failed part called the "Fuel level sending unit". The fuel level sending unit is located inside the gas tank and is part of a Modular assembly called the fuel pump assembly the fuel level sending unit is not sold separately, it comes as all one piece, see photo below. The reason the miles to empty works is that this is calculated by the engine control computer from various sensors on the engine, and it doesn't use the fuel level sender as one of the inputs to calculate the miles to empty figure. To replace the fuel level sensor in the fuel tank requires that the fuel tank be removed from the truck.

How To Replace a 2002 Ford Explorer Fuel Pump Module. Remember you are working with very flammable gasoline, be careful!

Prepare your
vehicle for fuel pump servicing. Position your vehicle on a hoist and place it in neutral. Release the fuel system pressure and drain the tank. Remove the fuel tank skid plates with a socket wrench and use a Hydraulic Floor jack to support the fuel tank. Loosen the bolts that retain the fuel tank support straps with a socket wrench, slowly drop the fuel tank down and disconnect the electrical connectors and then the fuel lines (you will need a special fuel line spring release tool) also disconnect the vapor tube fittings.
Release the fuel pump retaining lock ring by carefully rotating it using the fuel pump locking ring tool. Remove the lock ring first followed by the fuel pump. Use care to avoid damaging the fuel filter and float arm. Discard the old O-ring seal.
Install the new fuel pump using the items included in the kit, especially the new O-ring seal.
Complete the installation by reversing the removal procedure.

This is the fuel pump module that also contains the fuel level sensor that feeds the signal to the fuel gauge.

It means there is an error in the way miles to empty is calculated because your fuel level sensor isn't working. That's also why the low fuel indicator is on.

You may have to replace the cluster in the dash. Sometimes those fuses go. On my 750il the eml light went out on the dash and made the whole car go into limp mode.

1970 Ford F100 Gas Gauge Not Working

It may be the sending unit in the tank that needs replacing. Here's how you can check: Turn the key on and disconnect the sender unit at the gas tank. Ground the sender unit's wire with a jumper wire from the truck's harness to ground. Watch the gauge. If the gauge on the dash is good, grounding the sender wire will cause the gauge needle to react and should move to full. This would indicate a new sending unit is required. If the gauge doesn't move when the sender unit is grounded, the gauge is bad and needs replacing. Pull the instrument cluster out to replace the gas gauge. Likely any old ford gas gauge might work-back then, there were not so many production changes.

My gas gauge does not work

Easy fix, fill it with gas, write down the odometer mileage, keep track of it and after 150-250 miles put gas in it. Dodges are notorious for this problem. If you are lucky you can just replace the gauge in the dash. If not, you have to drop the gas tank, empty the gas out of it, take it apart and replace the float in the tank. My suggestion, keep track of your mileage. I have done this and it just sucks to fix it.

Put a battery in and started the car and the gas gauge doesn't registar or the miles to empty doesnt , trip meter nothing came back it all lighst up but registars 0. how do I get it back???? Thank you

You will need to drive the car for it to calculate the miles, when you remove the battery it looses all memory, try driving a few miles and see if it reads out again. good luck.
