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

11. Connect ECM/PCM connector terminal E7 to body

ground with a jumper wire.

12. Turn the ignition switch ON (II).

13. Measure voltage between ECM/PCM connector

terminal E17 and body ground.

Go to step 14.

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

14. Turn the ignition switch OFF.

15. Remove the jumper wire, and reconnect ECM/PCM

connector E (31P).

16. Open the SCS line with the HDS.

17. Turn the ignition switch OFF.

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

voltage between ECM/PCM connector terminal E17
and body ground within the first 2 seconds after the
ignition switch was turned on.

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 20.

19. Turn the ignition switch OFF.

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

21. Remove the access panel from the floor.

22. Measure voltage between fuel pump 5P connector

terminal No. 5 and body ground within the first
2 seconds after the ignition switch was turned on.

Go to step 28.

23. Turn the ignition switch OFF.

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

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

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

26. Turn the ignition switch ON (II).

27. Measure voltage between fuel pump 5P connector

terminal No. 5 and body ground.

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.

28. Turn the ignition switch OFF.

29. 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.

Before disconnecting fuel lines or hoses, relieve
pressure from the system by stopping the fuel pump
and disconnecting the fuel tube/quick connect fitting in
the engine compartment.

1. Remove the fuel fill cap.

2. Turn the ignition switch ON (II).

3. From the INSPECTION MENU of the HDS, select

Fuel Pump OFF, then start the engine, and let it idle
until it stalls.

4. Turn the ignition switch OFF.

NOTE:

• Do not allow the engine to idle above 1,000 rpm

or the ECM/PCM will continue to operate the fuel
pump.

• A DTC or a Temporary DTC may be set during

this procedure. Check for DTCs, and clear them
as needed (see page 11-3).

5. Turn the ignition switch OFF.

6. Make sure you have the anti-theft codes for the

radio, then write down the frequencies for the
radio’s preset buttons.

7. Disconnect the negative cable from the battery.

8. Check the fuel quick-connect fitting for dirt, and

clean it if needed.

9. Place a rag or shop towel over the quick-connect

fitting (A).

10. Disconnect the quick-connect fitting (A): Hold the

connector (B) with one hand, and squeeze the
retainer tabs (C) with the other hand to release
them from the locking tabs (D). Pull the connector
off.

NOTE:

• To prevent the remaining fuel in the fuel feed line

or hose from flowing out, use a rag or shop towel.

• Be careful not to damage the line (E) or other

parts.

• Do not use tools.
• If the connector does not move, keep the retainer

tabs pressed down, and alternately pull and push
the connector until it comes off easily.

• Do not remove the retainer from the line; once

removed, the retainer must be replaced with a
new one.

11. After disconnecting the quick-connect fitting, check

it for dirt or damage (see step 4 on page 11-370).

12. Reconnect the negative cable to the battery and do

these items:

• ECM/PCM idle learn procedure (see page 11-349).
• Power window control unit reset procedure

(see page 22-148).

• Enter the anti-theft codes for the radio, then enter

the customer’s radio station presets.

• Reset the clock.

1. Make sure you have the anti-theft codes for the

radio, then write down the frequencies for the
radio’s preset buttons.

2. Remove the glove box (see page 20-67), then

remove PGM-Fl main relay 2 (FUEL PUMP) (A) from
the under-dash fuse/relay box.

3. Start the engine, and let it idle until it stalls.

NOTE: If any DTCs are stored, clear and ignore
them.

4. Turn the ignition switch OFF.

5. Remove the fuel fill cap, and relieve the pressure in

the fuel tank.

6. Disconnect the negative cable from the battery.

7. Check the fuel quick-connect fitting for dirt, and

clean it if needed.

8. Place a rag or shop towel over the quick-connect

fitting (A).
