8. Start the engine and let it idle. Measure the fuel line pressure.
Zero or low
- FP circuit
- FP
- Fuel line (clogged)
- Fuel leakage inside pressure regulator
High
- Pressure regulator for high pressure cause
Fuel line pressure 375-450 kPa {3.9-4.5 kgf/cm2, 55-65 psi}
9. Observe the fuel pressure gauge indicator during heavy acceleration.
10. Verify that the fuel pressure fluctuation is within the specification during the test.
- PCM
- FP
- Pulsation damper
- Fuel line for improper routing, kinks or leakage
Fuel pressure fluctuation 365-450 kPa {3.8-4.5 kgf/cm2, 53-65 psi}
11. Turn the ignition switch to the LOCK position.
12. Measure the fuel hold pressure after 5 min.
- FP hold pressure
- Fuel injector for leakage
- Fuel line for improper routing, kinks or leakage
Fuel hold pressure More than 200 kPa {2.0 kgf/cm2, 29 psi}
13. Complete the BEFORE REPAIR PROCEDURE. (See BEFORE REPAIR PROCEDURE)
14. Disconnect the SST.
Note
15. Inspect the plastic fuel hose and fuel pipe sealing surface for damage and deformation, and replace as necessary.
16. Apply a small amount of clean engine oil to the sealing surface of the fuel pipe.
17. Reconnect the fuel main hose to the fuel distributor until a click is heard.
18. Lightly pull and push the quick release connector a few times by hand and verify that it can move 2.0-3.0 mm {0.08-0.11 in}
and it is connected securely.
19. Complete the AFTER REPAIR PROCEDURE. (See AFTER REPAIR PROCEDURE.)
