My gas guage has recently gone way past the full mark and now sits straight down (imagine the 6 on a clock) when the car is turned off. But when I start the car the needle goes up and sits under the peg (imagine a 9 on a clock). What could be the problem and how much of a cost am I looking at to get it back to normal (9 & 12)?

yeah knowing the make and model would help. however newer gm cars are notorious for this. the problem is actually in the dash assembly. mechanics have been taking the dash appart a just pulling the needle off, putting it back on past the peg. i know that sounds weird but my brother, "a gm certified tech" says that is how they were trained to do it and it really works. leave it to gm to make things really screwy. call the dealership and see if there is bullitin on it. it may be covered.

The most likely possibility is a faulty fuel sending unit. I don't know what your vehicle is, but most of them have the sender in the fuel tank as part of the fuel pump. This assembly is called a fuel pump module. Another possibility is that the actual fuel gauge is faulty, or there may be a problem with the wiring, connectors, voltage source that can cause it. Again, statistically the best possibility is a faulty sender, followed by a faulty gauge. This will need an electrical evaluation by a professional technician to determine which so that you don't throw a part at it that is unnecessary. You can find the best repair facilities by checking ASE.com and finding a Blue Seal shop. This is an elite certification given to only 3-4% of all shops, nationwide.

You failed to mention the make and model of your car, in my experience I would guess a mid to late 90's or newer GM vehicle, more often than not this is a bad fuel sender which is attached to the fuel pump also known as a module. It is not serviceable and must be replaced to fix the gauge, prob around 500 dollars, sorry and good luck.

check the fuse some vehicles have fuses that run the gauges. Also a thing you can try is find the wire that runs the gauge and ground it out really quickly than re-connect this can fixl the problem unless it is something else.

the sensor for the gas gauge might be bad. my mom had a car that the gas gauge acted strange. we took it in and they said it would cost $500, because the sensor is in the gas tank.
