FUEL PRESSURE CHECK

Work Procedure

INFOID:0000000010702870

FUEL PRESSURE RELEASE

1.

FUEL PRESSURE RELEASE

With CONSULT

1.

Turn ignition switch ON.

2.

Perform “ENGINE” in “WORK SUPPORT” mode with CONSULT.

3.

Start the 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 the 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.

>> INSPECTION END

FUEL PRESSURE CHECK

1.

FUEL PRESSURE CHECK

1.

Release fuel pressure.

2.

Connect fuel hose for fuel pressure check (B) to fuel pressure
gauge (A) (SST: ST19590000). Then, connect fuel hose for fuel
pressure check to fuel tube adapter (D) (SST: KV10120000) with
hose clamp (C).

CAUTION:

• Use suitable fuel hose for fuel pressure check (genuine

NISSAN fuel hose)

• To avoid unnecessary force or tension to hose, use moderately long fuel hose for fuel pressure

check.

• Wipe off oil or dirt from hose insertion part using cloth moistened with gasoline.
• Apply proper amount of gasoline on the hose insertion part.
• Use NISSAN genuine hose clamp (part number: 16439 N4710 or 16439 N4710)
• Install hose clamp to the hose end position within 1- 2 mm (0.04 - 0.08 in) and tighten hose clamp

to the specified torque.

3.

Disconnect quick connector and disconnect fuel feed hose from high pressure fuel pump. Refer to 

EM-

164, "Exploded View"

.

CAUTION:

• Make sure to release fuel pressure before removal of fuel line.
• Do the following procedure in the place where ventilation is good without the combustible.
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 this models do not have fuel return system.

FUEL PRESSURE CHECK

• Use fuel tube adapter (SST: KV10120000) and fuel pressure gauge (SST: ST19590000) to check fuel

pressure.

4.

Install fuel hose for fuel pressure check to high pressure fuel
pump with hose clamp.

CAUTION:

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

moistened with gasoline.

• Apply proper amount of gasoline on the hose insertion

part.

• 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).

• Install hose clamp to the hose end position within 1- 2 mm

(0.04 - 0.08 in) and tighten hose clamp to the specified torque.

• After connecting fuel hose for fuel pressure check, pull the hose with a force of approximately

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

5.

Install fuel pressure check adapter to quick connector of fuel
feed hose.

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 (A).

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> GO TO 2.

2.

CHECK FUEL HOSE

Check fuel hose for clogging.
Is the inspection result normal?

YES

>> Repair or replace the malfunctioning part.

NO

>> Replace fuel filter and fuel pump assembly. Refer to 

FL-18, "Exploded View"
