Fuel Pump: 3.2TL

  1. Listen for fuel pump operation noise at fuel injector rail under intake manifold cover. 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.
  2. Turn ignition switch off. Remove spare tire and fuel pump access panel to gain access to fuel pump. Disconnect fuel pump 5-terminal harness connector. Disconnect PGM-FI main relay 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 (Black/Yellow wire) and 5 (Red/White wire). See Figure. Go to next step.
  3. Turn ignition on. Using a voltmeter connected to ground, check for battery voltage at fuel pump harness connector terminal No. 5 (Black/Yellow wire). If battery voltage is not present, check for faulty circuit between fuel pump, PGM-FI relay and fuse No. 1 in driver's underdash fuse/relay box. See appropriate diagram in 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.
