• Never operate fuel pump when there is no fuel in lines.
• Tighten fuel hose clamps to the specified torque.

• Never depress accelerator pedal when starting.
• Immediately after starting, never rev up engine unnecessarily.
• Never rev up engine just prior to shutdown.

• When installing C.B. ham radio or a mobile phone, always

observe the following as it may adversely affect electronic
control systems depending on installation location.

- Keep the antenna as far as possible from the electronic con-

trol units.

- Keep the antenna feeder line more than 20 cm (8 in) away

from the harness of electronic controls.
Never let them run parallel for a long distance.

- Adjust the antenna and feeder line so that the standing-wave

radio can be kept smaller.

- Always ground the radio to vehicle body.

FUEL PRESSURE

ON-VEHICLE MAINTENANCE

FUEL PRESSURE

Fuel Pressure Check

INFOID:0000000005273910

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 two or three times to release all fuel pressure.

5.

Turn ignition switch OFF.

 Without CONSULT-III

1.

Remove fuel pump fuse (No.48) located in IPDM E/R.

2.

Start engine.

3.

After engine stalls, crank it two or three times to release all fuel
pressure.

4.

Turn ignition switch OFF.

5.

Reinstall fuel pump fuse after servicing fuel system.

FUEL PRESSURE CHECK

CAUTION:

Be careful not to scratch or get the fuel hose connection area dirty when servicing, so that the quick
connector o-ring maintains sealability.
NOTE:
• Prepare pans or saucers under the disconnected fuel line because the fuel may spill out. The fuel

pressure cannot be completely released because D40 models do not have fuel return system.

• Use Fuel Pressure Gauge Kit J-44321 and Fuel Pressure Adapter J-44321-6 to check fuel pressure.
1.

Release fuel pressure to zero. Refer to "FUEL PRESSURE RELEASE".

2.

Remove fuel hose using Quick Connector Release J-45488.
• Never twist or kink fuel hose because it is plastic hose.
• Never remove fuel hose from quick connector.
• Keep fuel hose connections clean.

3.

Install Fuel Pressure Adapter J-44321-6 and Fuel Pressure
Gauge (from kit J-44321) as shown in figure.
• Never 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.
• During fuel pressure check, check for fuel leakage from fuel

connection every 3 minutes.

7.

If result is unsatisfactory, go to next step.
