Work Procedure
INFOID:0000000006417061
FUEL PRESSURE RELEASE
With CONSULT-III
1.
Turn ignition switch ON.
2.
Perform “FUEL PRESSURE RELEASE” in “WORK SUPPORT” mode of “ENGINE” using 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 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:
• 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 J10 models do not have fuel return system.
1.
Release fuel pressure to zero.
2.
Prepare fuel hose for fuel pressure check B and fuel tube
adapter [SST: KV10118400] D, then connect fuel pressure
gauge A.
•
: To quick connector
•
: To fuel tube (engine side)
• C: Clamp
• Use suitable fuel hose for fuel pressure check (genuine NIS-
SAN fuel hose without quick connector).
• To avoid unnecessary force or tension to hose, use moder-
ately long fuel hose for fuel pressure check.
• Do not use the fuel hose for checking fuel pressure with dam-
age or cracks on it.
• Use Pressure Gauge to check fuel pressure.
3.
Remove fuel hose.
• Do not twist or kink fuel hose because it is plastic hose.

Connect fuel hose for fuel pressure check (1) to fuel tube
(engine side) with clamp (2) as shown in the figure.
• No.2 spool (5)
• Wipe off oil or dirt from hose insertion part using cloth moist-
ened with gasoline.
• Apply proper amount of gasoline between top of the fuel tube
(3) and No.1 spool (4).
• Insert fuel hose for fuel pressure check until it touches the
No.1 spool on fuel tube.
• 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.
5.
Connect fuel tube adapter to quick connector.
• A: Fuel pressure gauge
• B: Fuel hose for fuel pressure check
6.
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.
7.
Turn ignition switch ON and check for fuel leakage.
8.
Start engine and check for fuel leakage.
9.
Read the indication of fuel pressure gauge.
• Do not perform fuel pressure check with system operating.
Fuel pressure gauge may indicate false readings.
• During fuel pressure check, confirm for fuel leakage from fuel connection every 3 minutes.
10. If result is unsatisfactory, go to next step.
11. Check the following.
• Fuel hoses and fuel tubes for clogging
• Fuel filter for clogging
• Fuel pump
• Fuel pressure regulator for clogging
If OK, replace fuel pressure regulator.
If NG, repair or replace.
Tightening torque:
1 - 1.5 N·m (0.1 - 0.15 kg-m, 9 - 13 in-lb)
At idling:
Approximately 350 kPa (3.5 bar, 3.57 kg/cm

HOW TO SET SRT CODE
Always drive the vehicle in safe manner according to traffic conditions and obey all traffic laws.
NOTE:
*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.
