Note
• The stopper may be removed from the quick
connector. Take care not to loose it.
Reinstall it to the quick release connector
before reconnecting the fuel line.
• The locking coupler has two internal locking
tabs which retain the pulsation damper pipe.
Be sure that the tab on the locking coupler is
rotated until it stops to release two internal
locking tabs.
4. Push the SST quick release connector into the
fuel pipe and plastic fuel hose into the SST until a
click is heard.
5. Turn the lever parallel to the hose of the SST as
shown.
6. Connect the negative battery cable.
7. Verify that the vehicles for AT is at N range and
MT is at neutral position.
8. Start the engine and let it idle. Measure the fuel
line pressure.
• If not as specified, inspect the following:
Zero or low
FP circuit
FP
Fuel line (clogged)
Fuel leakage inside pressure regulator
High
Pressure regulator for high pressure cause
Fuel line pressure
375450 kPa {3.94.5 kgf/cm
9. Observe the fuel pressure gauge indicator during heavy acceleration.
10. Verify that the fuel pressure fluctuation is within the specification during the test.
• If not as specified, inspect the following:
PCM
FP
Pulsation damper
Fuel line for improper routing, kinks or leakage
Fuel pressure fluctuation
365450 kPa {3.84.5 kgf/cm
11. Turn the ignition switch to the LOCK position.
12. Measure the fuel hold pressure after 5 min.
• If not as specified, inspect the following:
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/cm
