Some cars have a second fuse box under the hood near the battery. See if your car doesn't have one of those.

SOURCE: Ran out of gas 90 toyota corolla fuel injection

Sounds like air in the fuel line. Try turning the key ON and pumping the gas pedal (it may take 10-15 times) and then try to start the car. You need to force gas through the fuel lines to dispel the air it was pumping when the car ran out of gas. If it doesn't work the first time, let it rest and repeat by pumping the gas. Best of luck!

SOURCE: 1990 toyota corolla, fuel/temperature gauges not working.

If you are handy with small hand tools and a Volt/Ohm meter then it would be worth a try to check the problem, older cards the fuel guage is problematic. In the tank in a wire wound resistor connected to the float in the tank, every time you change the fuel lever the wiper rubs the wires and over time it either breaks or gets coated with crud, it requires removing the sensor from the tank and cleaning it. To test however you can follow the wires to the tank and remove the connector, if you have a fuel pump in the tank then you will need to check the wiring diagram for the correct wires and colors. You then measure the resistance across the two wires for the sensor, open circuit means the part will require removel and repair, anything from zero to about 120 means it is probably working, you can also short the wires going back to the gauge and turn on the ignition switch but don't start the car, if it read full then remove the short and it should read empty, the gauge is working. Temp gauge same process just the sensor is under the hood, same process measure resisitance. If you are going to try this yourself I suggest a service manual from your local parts store. If you choose to then take it to a mechanic you already know what to expect. I don't suggest removing a fuel tank alone, it requires jacking up the card and having something to raise and lower the tank. You are working with flamable liquids and you can be seriously injured or killed. Take care folow instructions and you will be fine. Wish it were simpler but this is what a mechanic is going to do as well.
