Remove fuel tank filler cap. Listen for fuel pump operation noise at fuel tank filler. Fuel pump should operate for 2 seconds after ignition switch is turned on. If fuel pump operates as specified, fuel pump is okay. If fuel pump does not operate as specified, go to next step.
Turn ignition switch off. Remove rear seat cushion to gain access to fuel pump. On hatchback, remove spare tire lid and fuel pump access cover. On all models, disconnect fuel pump 2-pin harness connector. Disconnect PGM-FI main relay 7-pin connector located above driver's side kick panel, just left of fuse block. Connect a fused jumper wire between PGM-FI main relay harness connector terminals No. 4 and 5 (both Yellow/Green wires). See Fig 1. Go to next step.
Turn ignition on. Using a voltmeter connected to ground, check for battery voltage at fuel pump harness connector terminal No. 2 (Yellow/Green wire). If battery voltage is not present, check for faulty circuit in Yellow/Green wire between fuel pump and FUEL PUMP fuse. See WIRING DIAGRAMS article. Repair as necessary. If battery voltage is present, check fuel pump ground (Black/White wire). Repair as necessary. If ground is okay, replace fuel pump.
