Result- out of fuel early morning with family on highway. Temp gauge not working not over heating 00 f150 4x4 4. Resistance should range between 22. Going past full indicates the brown wire to the sender is not connected or the sender is bad. I have a 93 Bronco and the fuel gauge will go all kinds of crazy it will go from empty to full to way over full to anywhere in between while sitting still idling. I grounded the wires together.
