Relieve fuel pressure before servicing fuel system. See BASIC DIAGNOSTIC PROCEDURES
article in ENGINE PERFORMANCE.
- Remove fuel gauge sending unit. Connect ohmmeter between Green/Yellow wire or Black/Red wire, and Red wire of fuel gauge sending unit connector.
- Measure resistance with fuel gauge sending unit float in specified position. See FUEL GAUGE SENDING UNIT RESISTANCE table. If resistance is not as specified, replace fuel gauge sending unit.
