Fuel Gauge Sender
#16
Are you talking about the wires at the sender? Only the middle two are used. From there the signal goes to the PCM where it is finally sent to the Gauge cluster in your dash. The PCM reads the resistance and changes it into a data signal for the gauge to use. If you tested your sender in your hand it could still be bad. It would be real easy to hold it in such a way as to let the sliding resistor make contact and then not make contact once installed.
Hope this helps.

sending unit
My gauge goes the full range empty to full when you turn key on and off. The gauge hardley drops down and does not show much past 3/4 full when the tank is almost empty. When you use the high volume pumps, does that do a number on the sending unit?
