J32A3 engine

If you suspect a problem with the fuel pump, check that the fuel pump actually runs; when it is on, you will hear some noise if you listen to the fuel fill port with the fuel fill cap removed. The fuel pump should run for 2 seconds when the ignition switch is first turned on. If the fuel pump does not make noise, check as follows:

  1. Turn the ignition switch OFF.
  2. Remove the left kick panel (see TRIM REMOVAL/INSTALLATION - DOOR AREAS ), then remove PGM-FI main relay 2 (G) from the under-dash fuse/relay box.

  3. Turn the ignition switch ON (II).
  4. Measure voltage between PGM-FI main relay 2 4P connector terminal No. 4 and body ground.

    Is there battery voltage? 

    YES  -Go to step 5.

    NO  -

    • Replace PGM-FI main relay 1.
    • If needed replace the under-dash fuse/relay box.
  5. Measure voltage between PGM-FI main relay 2 4P connector terminal No. 1 and body ground.

    Is there battery voltage? 

    YES  -Go to step 6.

    NO  -

    • Check the No. 19 IG FUEL PUMP (15 A) fuse in the under-dash fuse/relay box.
    • If needed replace the under-dash fuse/relay box.
  6. Turn the ignition switch OFF.
  7. Connect PGM-FI main relay 2 4P connector terminal No. 3 to body ground with a jumper wire.

  8. Jump the SCS line with the HDS.
  9. Disconnect ECM/PCM connector E (31P).
  10. Check for continuity between body ground and ECM/PCM connector terminal E2.

    Is there continuity? 

    YES  -Go to step 11.

    NO  -Repair open in the wire between PGM-FI main relay 2 and the ECM/PCM (E2).

  11. Reinstall PGM-FI main relay 2.
  12. Connect ECM/PCM connector terminal E5 to body ground with jumper wire.

    Is there battery voltage? 

    YES  -Go to step 15.

    NO  -Replace PGM-FI main relay 2.

  15. Turn the ignition switch OFF.
  16. Reconnect ECM/PCM connector E (31P).
  17. Open the SCS line with the HDS.
  18. Turn the ignition switch OFF.
  19. Turn the ignition switch ON (II), and measure voltage between ECM/PCM connector terminal E2 and body ground within 2 seconds.

    Is there battery voltage? 

    YES  -Update the ECM/PCM if it does not have the latest software (see UPDATING THE ECM/PCM ), or substitute a known-good ECM/PCM (see SUBSTITUTING THE ECM/PCM ), then recheck. If the symptom/indication goes away with a known-good ECM/PCM, replace the original ECM/PCM (see ECM/PCM REPLACEMENT ).

    NO  -Go to step 20.

  20. Turn the ignition switch OFF.
  21. Remove the trunk floor trim panel (see TRIM REMOVAL/INSTALLATION - TRUNK AREA ).
  22. Remove the access panel from the floor.
  23. Turn the ignition switch ON (II), and measure voltage between fuel pump 5P connector terminal No. 5 and body ground within 2 seconds.
