There is a switch under the vehicle near the gas tank that may have something hung in it, like a tree limb...

There is none. But you can try disconnecting the wiring attached to the fuel sending unit and look at the fuel gauge. If it is giving you an empty reading, the fuel gauge is faulty and should be replaced.

This is usually caused by either the sender in the tank is bad and should be replaced, or the gauge is not reading correctly and needs to be repaired or replaced.

I was having the same problem with my 99 explorer. What I discovered was that the overflow tank for the radiator was empty and was causing a false reading by the temp gauge.

That depends entirely on the vehicle and on how accurate the gauge is.

The way to test the gauge is to unhook the wires to the sender and the gauge should read empty. Now, ground the sensor wire and the gauge should go all the way past the full level. If this happens your wiring and gauge are fine.

probably no gas, if there is gas then your gauge in the tank is broken or frozen

Either the gauge is broken or the sender is broken.

with a full tank of gas the gauge will drop to "E" then after a few seconds it will jump back to correct reading.
