This sounds like a grounded wire, look at all wires under the vehicle going to the fuel tank.

Do I have a bad fuel pump


Not symptoms of a pump. Sounds more like a bad idle air control valve. run some fuel system cleaned in it and run a full tank of gas to see if it changes.

Gas gage stopped regestering below 1/2 full


mcdevito75 here, Hello john, the sending unit in the gas tank could be faulty of stuck, try leaning against one of the back fenders to move the body of the car from side to side to try to free up the sending unit. You may have to live with it unless yoyur local shop changes the sending unit in the gas tank.

Most gauges are set up this way to give you a bit of "margin" between "e" and stuck on the road.Sometimes this is set a bit too high but adjusting it is not worth the $. Additionally, there is generally about a gallon of fuel remaining in tank that the pump cannot reach. This protects you against most heavy debris (rust etc) and water that acumulates there (even in the most well maintained vehicles) which would otherwise easily enter the fuel system. As long as you are not running out at 1/4 tank or anything, you are OK.
