2002-05 Owners. As of August 2022 there is now an entire suspension kit for sale! Scroll down to the bottom of the first post click here.
Have you checked for any OBDII codes? Also, run seafoam through two tanks of gas.Goes to full; responds full range with ignition on/off. Only goes below half when ignition is off.
I am having the same problem with my wife’s 2004, gage stays at half all the time even when we fill the tank. Replaced fuel pumps and the fuel gage worked as it should. Now it’s stuck at half again. Car runs fine but this problem just won’t go away.
This may help. It describes how the fuel tank & its two pumps function.
