I recently noticed that my gas gauge was not moving while I was driving...It was on the half tank level...I proceeded to go and fill it and now it will not move from the full tank level...I drive about 30 miles a day so i know my gas gauge should be moving down

what could be the possible issue and how much could it cost to fix..

thanks

Sound like the gauge sending unit in the fuel tank is either stuck or bad.
Let's try something; When you know your fuel level is about a 1/4 tank or lower, take a baseball bat, rubber hammer or something similar and rap the bottom of the tank a few times. Then, see if the gauge reads in the lower range. If yes, the sender is probably sticking and will probably stick again over time. The sending unit is in the tank and the tank will have to be removed to replace it. Also, the bad part, I believe the gauge sender and fuel pump are an assembly and have to be changed as a unit. Estimated repair cost. $300 to 500.
