FUEL LINE PRESSURE INSPECTION [L3 R.H.D.]


id0114a2800500

Warning
• Fuel line spills and leakage from the pressurized fuel system are dangerous. Fuel can ignite and cause death or serious injuries and damage. To prevent this, always carry out the following procedure with the engine stopped.

1. Perform the 'Fuel Line Safety Procedure' referring to the BEFORE SERVICE PRECAUTION. (See BEFORE SERVICE PRECAUTION [L3].)

2. Disconnect the negative battery cable.

3. Disconnect the quick release connector of the engine compartment side. (See QUICK RELEASE CONNECTOR REMOVAL/INSTALLATION [L3].)

4. Turn the lever of the SST parallel to the hose as shown in the figure.

5. Insert the SST quick release connector into the fuel pipe until a click is heard.

6. Verify that the installation is secure by pulling the quick release connector.

7. Verify that the selector lever is in the N range, and start the engine.

8. Measure the fuel line pressure while idling.

• If it is not within the specification, inspect the following:
Zero or low
- Fuel pump
- Fuel pump circuit
- Fuel line clogging
- Fuel leakage inside pressure regulator
High
- Pressure regulator clogging
Standard
380-420 kPa {3.88-4.28 kgf/cm2, 55.2-60.9 psi}

9. Observe the fuel pressure gauge indicator during heavy acceleration.

• If it is not within the specification, inspect the following:
- PCM
- Fuel pump
- Fuel line clogging or leakage
Standard
380-420 kPa {3.88-4.28 kgf/cm2, 55.2-60.9 psi}

10. Turn the ignition switch to the LOCK position.

11. Measure the fuel hold pressure after 5 min.

• If it is not within the specification, inspect the following:
- Fuel pump
- Fuel injector leakage
- Fuel line leakage
Standard
176 kPa {1.79 kgf/cm2, 25.5 psi} or more

12. Perform the 'Fuel Line Safety Procedure' referring to the BEFORE SERVICE PRECAUTION [L3]. (See BEFORE SERVICE PRECAUTION [L3].)

13. Disconnect the SST.

14. Connect the quick release connector. (See QUICK RELEASE CONNECTOR REMOVAL/INSTALLATION [L3].)

15. Inspect all parts by performing the AFTER SERVICE PRECAUTION. (See AFTER SERVICE PRECAUTION [L3].)
