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.
NOTE:
• Prepare pans or saucers under the disconnected fuel line because the fuel may spill out. The fuel
pressure cannot be completely released because C11 models do not have fuel return system.
• 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 seal abil ity 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 readin gs due to varying engine load and changes in
manifold vacuum.
1. Release fuel pressure to zero. Refer to "FUEL PRESSURE RELEASE".
2. Prepare fuel hose for fuel pressure check B and fuel tube adapter (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 (genuineNISSAN 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. Refer to EM-152, "
Removal and Installation".
• Do not twist or kink fuel hose because it is plastic hose.
4. 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 positi on 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 f uel 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.
12. 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.
13. Before disconnecting Fuel Pressure Gauge and Fuel Pressure Adapter J-44321-6, release fuel pressure to zero. Refer to "FUEL PRESSURE RELEASE".At idling: Approximately 350 kPa (3.57 kg/cm

TROUBLE DIAGNOSIS
Trouble Diagnosis IntroductionINFOID:0000000005532412
INTRODUCTION
The engine has an ECM to control major systems such as fuel con-
trol, ignition control, idle air control system, etc. The ECM accepts
input signals from sensors and instantly
drives actuators. It is essen-
tial that both input and output signals are proper and stable. At the
same time, it is important that there are no malfunctions such as vac-
uum leaks, fouled spark plugs, or other malfunctions with the engine.
It is much more difficult to diagnose an incident that occurs intermit-
tently rather than continuously. Most intermittent incidents are
caused by poor electric connections or improper wiring. In this case,
careful checking of suspected circuits may help prevent the replace-
ment of good parts.
A visual check only may not find t he cause of the incidents. A road
test with CONSULT-III (or GST) or a circuit tester connected should
be performed. Follow the Work Flow on "WORK FLOW".
Before undertaking actual checks, take a few minutes to talk with a
customer who approaches with a driv ability complaint. The customer
can supply good information about such incidents, especially inter-
mittent ones. Find out what symptoms are present and under what
conditions they occur. A Diagnosti c Worksheet like the example on
"Worksheet Sample" should be used.
Start your diagnosis by looking for conventional malfunctions first.
This will help troubleshoot drivability malfunctions on an electroni-
cally controlled engine vehicle.

DIAGNOSTIC WORKSHEET
Description
There are many operating conditions
that lead to the malfunction of
engine components. A good grasp of such conditions can make trou-
bleshooting faster and more accurate.
In general, each customer feels differently about an incident. It is
important to fully understand the symptoms or conditions for a cus-
tomer complaint.
Utilize a diagnostic worksheet as shown in the following "Worksheet
Sample" in order to organize all the information for troubleshooting.
Some conditions may cause the MI L to come on steady or blink and
DTC to be detected. Examples:
• Vehicle ran out of fuel, which caused the engine to misfire.
• Fuel filler cap was left off or incorrectly screwed on, allowing fuel to evaporate into the atmosphere.
