Fuel gage wont read past 1/2 mark when using fuel

You replaced the fuel gauge stepper motor two times ? Did you do it correctly ?

Fuel Gage
The IPC displays the fuel level as determined by the PCM. The IPC receives a class 2 message from the PCM indicating the fuel level percent. The fuel gage defaults to empty if:
• The PCM detects a malfunction in the fuel level sensor circuit.
• The IPC detects a loss of class 2 communications with the PCM.
When the fuel level is less than a pre-determined value, the low fuel indicator illuminates.
Reviewing the fuel system description will further explain how the system functions. Refer to Fuel System Description .

Did you try replacing the fuel level sensor ? Check for DTC'S diagnostic trouble codes ?

that is normal--it will come down as you use the fuel in the tank

Try un hooking battery.

Only thing I can tell, with all you've checked, is the power to the gage isn't there. If the tank sending unit ground to frame is not connected, the gage will go past the full mark. No power to the gage it will stay at empty side. Power goes from fuse to gage, gage to sending unit and back to gage. Make sure the fuse is good on both sides of it. The gage just isn't getting power from the fuse.

probably not all that difficult to fix it you have patience. The needle going way past full is an indication of a short before the sender unit or in the sender unit. Pull the power wire from the sender unit and see what the gauge does. IT should stay on the empty mark. IT may be just a fuel sender unit .

u need to change this gauge or try to dissasseble and clean it very well then try to install it back again

you must open the fuel tank and pullout the sensor which is mostly a float with a variable resistance and recalibrate it . so i think you shoul see a mechanic

TRY REPLACING FUEL PUMP IF IN TANK THE FUEL GAUGE GET ITS SINGAL FROM THERE

It sounds like the fuel level sending unit located on the fuel pump is malfunctioning. The solution for this is to have it replaced. You can do this yourself but I wouldn't recommend it as the vehicle needs to be lifted and the fuel tank needs to be dropped out. This can be preformed for about 100-150 in most shops.

I need to know if the other gauges are accurate. There is a voltage regulator mounted on the back side of the dash that can go bad and often does, that will make the other gauges inaccurate also.
