All dashboard instrumentation failed while driving
After getting gas, I pulled out on the highway and my gas tank read Empty and the low fuel message showed on the message center ... even though the miles of gas left showed 340. About 1/2 mile later, all other monitors and inside dash lights failed. Any ideas? I'm a single mom and I do not like to go to the repair shop without a basic understanding of what's wrong.

Fuel gauges are not meant to be precision instruments. You might want to fill up a 2 gallon can and drive the car until it runs out of fuel to see how low the gauge will go before it's really empty. Use the 2 gallons to get back to a filling station.
I once spent three working days trying to get a 1972 Chrysler to read full when it's full, half when it's half and quarter tank when the tank has a quarter amount of fuel. The customer did not want to accept anything else, but in the end all I did was to get close, not exact.
It is possible that the fuel float in the gas tank is "drowned", that is, the plastic float might have a slow leak and some fuel found its way inside. This will cause the float to submerge slightly and give you a low reading. To check this you will have to remove the float unit from the tank.
In any case, if you feel up the job (not easy) remove the float unit from the tank and manually move it up and down while checking the meter reading. You can bend the wire holding the float to correct misreadings.
Personally, I wouldn't bother, just be aware that when the reading is low, feel safe that you still have enough fuel to get to the next filling station.
sounds like a faulty sender unit or your just realy low on fuel before you spend any money on repairs try filling the tank up with fuel as if its been low for a long time the sender unit in the tank may be sticking the fuel will lube it and may start working again
Traditionally when the fuel light comes on you have about 1/16 of a tank left. Depending on weight in your car and weather your driving highway or in town and the speed you are driving as well as the quality of gas and how efficient your car run (MPG) on average just a few miles. I recommend you get some gas before that light comes on. Gauges are never perfect and it may leave you stranded sometime.
Sounds like float in fuel tank is sticking. Usually caused by using cheap gas. Fill it up and add a bottle of STP gas treatment. It might take more then one tankful w/STP to clean it completely. TIP: don't rely on the computer generated "mileage left" especially when that low on fuel, that is only an estimate. And also don't let it get that low on a regular basis because it will damage your fuel pump, fuel is used to cool electric pump in fuel tank and running it that low will shorten the life of your fuel pump.
Hello. Before getting involved in real repairs, dump a bottle of fuel injector cleaner in your fuel tank. It may clean your sending units enough to get them working again. The chances of success are only about 50%, but the cost is very low. Redline, Chevron, and others make good fuel injection cleaner.
Assuming nobody stole all of your gas, the fuel level sending unit is bad, the wiring to it is bad, or the instrument panel is failing.
The wiring can be accessed inside the trunk, on the left side, by pulling the carpeting up. The sending unit should read about 35 ohms when full and 235 ohms when the tank is empty. My Haynes manual says the wires are Purple, and Black-White.
If the sending unit reads correctly then the wiring to the instrument panel, or the panel itself is malfunctioning.
If it is the sending unit: the sending unit is attached to the fuel pump inside the fuel tank. You must remove the fuel tank to replace it. While you are in their you might as well put a new fuel pump in.
You weren't low on gas - your fuel tank sending unit is failing and needs replacement. It's inside the tank and usually can be replaced without replacing the fuel pump as well - don't get suckered into that.
check the grounds on your fuel tank sending unit,must drop the tank to do this. with the tank down,remove the ground and look at your fuel gauge it should read full or empty,if it does not it may be a sending unit
