Gas gauge not working

[meatball]

On my way home from KIA I notice my gas gauge wasn't working. KIA installed a new fuel tank and sending unit, they broke the fuel tank pressure sensor. So what I want to know is does the fuel tank pressure sensor have anything to do with gas gauge from working or is there a plug for the gas gauge?


and to who it was the one who told me about the keyway, I thank you because majority of the problems with the way my kia was running, that keyway really made a big difference. I fixed it and now it runs great. Thank You.

Did the dealer replace the entire fuel pump assembly, and was it a new unit?

Was the tank a new replacement? I only ask because if both were new, then it should not be a major cost (labor $$$) issue to pull the fuel pump & sender unit quickly to check..

If so, I'd be calling the Service Manager and explain the problem - it should be under warranty.

re: tank pressure sensor, I'd be explaining that to the dealer also. If they have the car back in the shop for the gauge diagnosis, maybe they will work with you on getting that fixed up also.

If no joy from the dealership, then you will need to do some electrical testing at the fuel pump to check voltage -> to see where the issue is, e.g.: the tank level sender, or in the wiring in-between.

(And source a replacement tank pressure sensor from OEM / 3rd-party vendor, or salvage yard..)

To answer your question, yes, there should be (2) plugs back at the tank: (1) for the fuel pump & fuel gauge, (1) for the tank pressure sensor.

i see your in PA i dont know how good the dealer is there but im in regina and im sure we can help you if they dont. this is something that they should address. im assuming that it worked before and if it didint and thats why you took it in then they are responsible for that

Yea, that gas gauge worked before I took it in. Looking at my receipt it shows the fuel tank, pump assembly.

Usually the "sending" unit for the fuel gauge is located on/near the fuel pump
ass'y. they probably either damaged yours or they created a problem with the
wiring when they replaced the pump. I would call the dealer and explain the gauge doesn't work and let them know "you know" where it's located and "gently" let them know it's their problem to repair.

the dealer told me that once i replace the tank pressure sensor the gas gauge will work again.

That is odd, I thought that the gauge works off a float. Sounds to me like the dealer is full of BS but I am old and have been wrong before. Make them fix the pressure sensor cause they broke it and see if it works.
Keep taking it back until it is repaired correctly.
