FUEL PRESSURE RELEASE

 With CONSULT-III

1.

Turn ignition switch ON.

2.

Perform “FUEL PRESSURE RELEASE” in “WORK SUPPORT” mode with CONSULT-III.

3.

Start engine.

4.

After engine stalls, crank it 2 or 3 times to release all fuel pressure.

5.

Turn ignition switch OFF.

 Without CONSULT-III

1.

Remove fuel pump fuse located in IPDM E/R.

2.

Start engine.

3.

After engine stalls, crank it 2 or 3 times to release all fuel pressure.

4.

Turn ignition switch OFF.

5.

Reinstall fuel pump fuse after servicing fuel system.

FUEL PRESSURE CHECK

CAUTION:

Before disconnecting fuel line, release fuel pressure from fuel line to eliminate danger.
NOTE:
• Prepare pans or saucers under the disconnected fuel line because the fuel may spill out. The fuel

pressure cannot be completely released because J32 models do not have fuel return system.

• Be careful not to scratch or get the fuel hose connection area dirty when servicing, so that the quick

connector o-ring maintains seal ability.

1.

Release fuel pressure to zero.

2.

Remove fuel hose using Quick Connector Release.
• Do not twist or kink fuel hose because it is plastic hose.
• Keep fuel hose connections clean.

3.

Install Fuel pressure adapter (B) and Fuel pressure gauge (A)
as shown in figure.
• Do not distort or bend fuel rail tube when installing fuel pres-

sure gauge adapter.

• When reconnecting fuel hose, check the original fuel hose for

damage and abnormality.

4.

Turn ignition switch ON (reactivate fuel pump) and check for fuel
leakage.

5.

Start engine and check for fuel leakage.

6.

Read the indication of fuel pressure gauge kit.
• During fuel pressure check, check for fuel leakage from fuel

connection every 3 minutes.

7.

If result is unsatisfactory, go to next step.

8.

Check the following.
• Fuel hoses and fuel tubes for clogging
• Fuel filter for clogging
• Fuel pump
• Fuel pressure regulator for clogging

9.

If OK, replace fuel pressure regulator.
If NG, repair or replace malfunctioning part.

EVAPORATIVE EMISSION SYSTEM

Inspection

INFOID:0000000003932067

1.

Visually inspect EVAP vapor lines for improper attachment and for cracks, damage, loose connections,
chafing and deterioration.

2.

Check EVAP canister as per the following:

a.

Block port (B). Orally blow air through port (A).
Check that air flows freely through port (C).

b.

Block port (A). Orally blow air through port (B).
Check that air flows freely through port (C).

3.

Inspect fuel tank filler cap vacuum relief valve for clogging, stick-
ing, etc.

a.

Wipe clean valve housing.

b.

Check valve opening pressure and vacuum.

c.

If out of specification, replace fuel filler cap as an assembly.
