FUEL PUMP INSPECTION
1. Connect the data link connector terminals F/P and GND with a jumper wire as shown.
2. Remove the fuel filler cap.
3. Turn the ignition switch to ON.
4. Listen at the filler inlet for the operational sound of the fuel pump.
5. Install the fuel filler cap.

Fuel Pump Harness Connector:




6. If no sound was heard, measure the voltage between terminal A of the vehicle harness side fuel pump connector and a ground (in the RH trunk compartment trim).

Voltage: B+

7. If the voltage is not correct, check the fuel pump relay and related wiring harness.
8. If the voltage is correct, check for continuity between terminals A and D of the fuel pump side connector (in the RH trunk compartment trim).

Fuel Pump Connector:




9. If there is continuity, check fuel pump ground circuit for open.
10. If there is no continuity, check for continuity between terminals A and D of the fuel pump connector as shown. (Underside of body)
11. If there is continuity, check terminal A and/or D harness between fuel pump connector to vehicle harness.
12. If there is no continuity, remove the fuel tank and replace the fuel pump.




HOLD PRESSURE

WARNING: Fuel line spills and leaks are dangerous. Fuel can ignite and cause serious injuries or death and damage. Fuel can also irritate skin and eyes. To prevent this, always complete the "Fuel Line Safety Procedures".




1. Disconnect the negative battery cable.
2. Connect a fuel pressure gauge to the fuel filter and plug the outlet of the gauge as shown. (Install clamps as shown.)
3. Connect the negative battery cable.




4. Connect data link connector terminals F/P and GND with a jumper wire.
5. Turn the ignition switch to ON for 10 sec. to operate the fuel pump.
6. Turn the ignition switch to OFF and disconnect the jumper wire.
7. Observe the fuel pressure after 5 min..

Fuel pressure, More than 340 kPa (50 psi)

8. If not specified, replace the fuel pump.




FUEL PUMP MAXIMUM PRESSURE

WARNING: Fuel line spills and leaks are dangerous. Fuel can ignite and cause serious injuries or death and damage. Fuel can also irritate skin and eyes. To prevent this, always complete the "Fuel Line Safety Procedures".




1. Disconnect the negative battery cable.
2. Connect a fuel pressure gauge to the fuel filter and plug the outlet of the gauge as shown. (Install clamps as shown.)
3. Connect the negative battery cable.




4. Connect data link connector terminals F/P and GND with a jumper wire.
5. Turn the ignition switch to ON to operate the fuel pump.
6. Measure the pump maximum pressure.

Fuel pump maximum pressure 450-630 kPa (64-92 psi)

7. Turn the ignition switch to OFF and disconnect the jumper wire.
8. If not as specified, replace the fuel pump.
