Fuel Sending Unit
Turn ignition off. Remove fuel sending unit from fuel tank. See FUEL PUMP under REMOVAL & INSTALLATION. Connect an ohmmeter across fuel pump 5-pin connector terminals No. 2 and 3 and measure resistance for each float position. See Fig 1. Move float arm and ensure resistance is as specified. See FUEL SENDING UNIT RESISTANCE table. If resistance is not as specified, replace fuel sending unit.

|---|---|
| Full | About 1-3 |
