FUEL PRESSURE RELEASE

1.

FUEL PRESSURE RELEASE

With CONSULT

1.

Turn ignition switch ON.

2.

Perform “FUEL PRESSURE RELEASE” in “WORK SUPPORT” mode of “ENGINE” using CONSULT.

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

1.

Remove fuel pump fuse 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.

>> END

FUEL PRESSURE CHECK

CAUTION:

• Before disconnecting fuel line, release fuel pressure from fuel line to eliminate danger.
• The fuel hose connection method used when taking fuel pressure check must not be used for other

purposes.

• Be careful not to scratch or put debris around connection area when servicing, so that the quick

connector maintains sealability with O-rings inside.

• Do not perform fuel pressure check with electrical systems operating (i.e. lights, rear defogger, A/C,

etc.) Fuel pressure gauge may indicate false readings due to varying engine load and changes in
manifold vacuum.

NOTE:
Prepare pans or saucers under the disconnected fuel line because the fuel may spill out. The fuel pres-
sure cannot be completely released because F15 models do not have fuel return system.

1.

FUEL PRESSURE CHECK

1.

Release fuel pressure to zero.

2.

Prepare fuel hose for fuel pressure check (B) and fuel tube
adapter [SST: KV10120000] (D), then connect fuel pressure
gauge (A).

CAUTION:

•  Use suitable fuel hose for fuel pressure check (genuine

NISSAN fuel hose without quick connector).

• To avoid unnecessary force or tension to hose, use mod-

erately long fuel hose for fuel pressure check.

• Do not use the fuel hose for checking fuel pressure with damage or cracks on it.
• Use Pressure Gauge to check fuel pressure.

3.

Remove fuel hose.

CAUTION:

Do not twist or kink fuel hose because it is plastic hose.

Connect fuel hose for fuel pressure check (1) to high pressure
fuel pump with clamp (2) as shown in the figure.

CAUTION:

• Wipe off oil or dirt from hose insertion part using cloth

moistened with gasoline.

• Apply proper amount of gasoline between top of the high

pressure fuel pump (3) and spool (4).

• Insert fuel hose for fuel pressure check until it touches

the spool on high pressure fuel pump.

• Use NISSAN genuine hose clamp (part number: 16439

N4710 or 16439 40U00).

• When reconnecting fuel line, always use new clamps.
• Use a torque driver to tighten clamps.

• Install hose clamp to the position within 1 - 2 mm (0.04 - 0.08 in).
• Make sure that clamp screw does not contact adjacent parts.
• After connecting fuel hose for fuel pressure check, pull the hose with a force of approximately 98

N (10 kg, 22 lb) to confirm fuel tube does not come off.

5.

Connect fuel tube adapter to quick connector.

6.

Turn ignition switch ON and check for fuel leakage.

7.

Start engine and check for fuel leakage.

8.

Read the indication of fuel pressure gauge.

CAUTION:

• Do not perform fuel pressure check with system operat-

ing. Fuel pressure gauge may indicate false readings.

• During fuel pressure check, confirm for fuel leakage from

fuel connection every 3 minutes.

Is the inspection result normal?

YES

CHECK FUEL HOSES

1.

Check the following.

-

Fuel hoses for clogging

-

Fuel filter for clogging

-

Low pressure fuel pump 

-

Fuel pressure regulator for clogging

Is the inspection result normal?

YES

>> Replace fuel pressure regulator.

OUTLINE

In order to set all SRTs, the self-diagnoses as in the “SRT ITEM” table must have been performed at least
once. Each diagnosis may require actual driving for a long period of time under various conditions.

SRT ITEM

The table below shows required self-diagnostic items to set the SRT to “CMPLT”.

*1: Though displayed on the CONSULT screen, “HO2S HTR” is not SRT item.
*2: If completion of several SRTs is required, perform driving patterns (DTC confirmation procedure), one by
one based on the priority for models with CONSULT.

HOW TO SET SRT CODE

Always drive the vehicle in safe manner according to traffic conditions and obey all traffic laws.

*1: Depress the accelerator pedal until vehicle speed is 90 km/h (56 MPH), then release the accelerator pedal
and keep it released for more than 10 seconds. Depress the accelerator pedal until vehicle speed is 90 km/h
(56 MPH) again.
*2: Checking the vehicle speed with GST is advised.
• The time required for each diagnosis varies with road surface conditions, weather, altitude, individual driving

habits, etc.

• “Zone A” is the fastest time where required for the diagnosis under normal conditions*. If the diagnosis is not

completed within “Zone A”, the diagnosis can still be performed within “Zone B”.
