Gauge Reads Full When Tank Is Empty

  1. Disconnect fuel tank sending unit connector. Turn ignition switch to "RUN" position. Wait one minute for fuel gauge to respond.
  2. If gauge reads "E", replace fuel gauge sender. If gauge reads "F", check Red/White gauge wire for short-to-ground, instrument cluster printed circuit and fuel gauge connections for damage. If printed circuit and gauge connections are okay, replace fuel gauge.
