- Turn ignition switch to OFF. Connect Subaru Select Monitor (SSM) to data link connector. Turn ignition switch and SSM switch ON. Start engine and select SSM function mode F17 (fuel temperature is indicated in °F). If value is greater than 300°F, go to step 2). If value is less than 3). If value is not less than - 40°F, repair poor contact in ECM connector, repair poor contact at fuel pump connector or repair poor contact in any coupling between ECM and fuel pump.
- Turn ignition switch OFF. Remove fuel pump access cover. Disconnect connector from fuel pump. Turn ignition and SSM ON and select function mode F17. If indicated value is less than - 40°F, replace fuel temperature sensor. If value is not less than - 40°F, repair short circuit in harness between ECM and fuel pump connector.
- With ignition OFF and access cover removed, disconnect fuel pump connector. Turn ignition switch ON. Measure voltage between fuel pump connector R38, terminal No. 2 and ground. If voltage is 4 volts or more, go to next step. If voltage is less than 4 volts, repair open circuit between ECM and fuel pump connector, repair poor contact in ECM connector, repair poor contact in fuel pump connector or repair poor contact in any coupling in wiring harness between ECM and fuel pump connector.
- Turn ignition switch to OFF. Measure resistance between fuel pump connector terminal No. 3 and ground. If resistance is 5 ohms or less, replace fuel temperature sensor. If resistance is more than 5 ohms, repair open in harness between ECM and fuel pump connector, repair poor contact in ECM connector, repair poor contact in fuel pump connector or repair poor contact in any coupling in harness between ECM and fuel pump connector.
