Hello,

First check your fuses if they are all good check the wires running from the sensor that tells the fuel gauge to fluctuate depending on how much gas is in the tank, what you may have done is when changing the fuel pump, you may have unplugged the sensor that tells how much gas is in the tank and you may have forgot to plug it back, if all these check out there is a fuel pump balance module that goes out in these cars, Here is a fuel pump wiring diagram and location of the module so you can do some testing and replace the module to get the problem fixed.

Please let us know what happens so it will help others.

Cheers, Ken
