fuel gauge won't work on 1994 Buick LeSabre

I changed the fuel pump on this car and now my fuel gauge only shows an empty tank.What went wrong? The fuel gauge worked fine before I changed the fuel pump.

On the pump, there is a fuel gauge sending unit, the float/arm that was attached to the unit. You may have bent the arm, knocked the float off, disconnected the wiring etc. I would check the wiring first, and then you will have to remove the unit to see if it looks ok.
Good Luck, let us know what you end up finding out!
