9. Reinstall PGM-FI main relay 2 (FUEL PUMP).

10. Connect ECM/PCM connector terminal E7 to body

ground with a jumper wire.

11. Turn the ignition switch ON (II).

12. Measure voltage between ECM/PCM connector

terminal E1 and body ground.

Go to step 13.

Replace PGM-FI main relay 2 (FUEL PUMP).

13. Turn the ignition switch OFF.

14. Reconnect ECM/PCM connector E (31P).

15. Turn the ignition switch ON (II), and measure

voltage between ECM/PCM connector terminal E1
and body ground within 2 seconds.

Update the ECM/PCM if it does not have the

latest software, or substitute a known-good ECM/
PCM (see page 11-6), then recheck. If the symptom/
indication goes away with a known-good ECM/PCM,
replace the original ECM/PCM (see page 11-284).

Go to step 16.

16. Turn the ignition switch OFF.

17. Remove the rear seat cushion (see page 20-85).

18. Remove the access panel from the floor.

19. Turn the ignition switch ON (II), and measure

voltage between fuel pump 5P connector terminal
No. 5 and body ground within 2 seconds.

Go to step 24.

Go to step 20.

20. Turn the ignition switch OFF.

21. Remove PGM-FI main relay 2 (FUEL PUMP).

22. Connect PGM-FI main relay 2 (FUEL PUMP) 5P

connector terminals No. 1 and No. 2 with a jumper
wire.

23. Turn the ignition switch ON (II), and measure

voltage between fuel pump 5P connector terminal
No. 5 and body ground within 2 seconds.

Replace PGM-FI main relay 2

(FUEL PUMP).

Repair open in the wire between PGM-FI main

relay 2 (FUEL PUMP) and the fuel pump 5P
connector.

24. Turn the ignition switch OFF.

25. Check for continuity between fuel pump 5P

connector terminal No. 4 and body ground.

Replace the fuel pump.

Repair open in the wire between the fuel

pump 5P connector and G501.

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 glove box (see page 20-67), then

remove PGM-FI main relay 2 (FUEL PUMP) (A).

3. Turn the ignition switch ON (II).

4. Measure voltage between PGM-FI main relay 2

(FUEL PUMP) 5P connector terminal No. 5 and
body ground.

Go to step 5.

Repair open in the wire between PGM-FI main

relay 1 (FI MAIN) and PGM-FI main relay 2 (FUEL
PUMP).

Go to step 6.

Repair open in the wire between the under-

dash fuse/relay box and PGM-FI main relay 2 (FUEL
PUMP).

6. Turn the ignition switch OFF.

7. Jump the SCS line with the HDS.

8. Disconnect ECM/PCM connector E (31P).

9. Check for continuity between PGM-FI main relay 2

(FUEL PUMP) 5P connector terminal No. 3 and
ECM/PCM connector terminal E17.

Go to step 10.

Repair open in the wire between PGM-FI main

relay 2 (FUEL PUMP) and the ECM/PCM (E17).
