Test D - Fuel Level Always Reads Full

Perform fuel level sensor test. See FUEL LEVEL SENSOR under COMPONENT TESTING. If level sensor is okay, go to next step. If level sensor tests bad, replace level sensor and retest system. Perform fuel gauge test. See FUEL GAUGE  under COMPONENT TESTING. If fuel gauge is okay, repair short in Yellow wire between cluster connector C249 on vehicles without tachometer (C254 with tachometer) and fuel level sensor and retest system. If fuel gauge tests bad, replace fuel gauge and retest system.
