- 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. Disconnect fuel pump 10-pin harness connector. Disconnect PGM-FI main relay 4-pin and 8-pin harness connectors located to right of steering column. Connect a fused jumper wire between PGM-FI main relay harness connector "A" terminal No. 2 (Yellow wire) and harness connector "B" terminal No. 5 (Red/White wire). 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. 7 (Yellow wire). If battery voltage is not present, check for faulty circuit between fuel pump, fuel pump relay, PGM-FI relay and fuel pump fuse located in underdash fuse/relay block. See WIRING DIAGRAMS article. Repair as necessary. If battery voltage is present, check fuel pump ground (Black wire). Repair as necessary. If ground is okay, replace fuel pump.
