lTo avoid unnecessary force or tension to hose, use moderately long fuel hose for fuel pressure check.
lDo not use the fuel hose for checking fuel pressure with damage or cracks on it.
lUse Pressure Gauge to check fuel pressure.
3. Remove fuel hose. Refer toEM-17, "
INTAKE MANIFOLD".
lDo not twist or kink fuel hose because it is plastic hose.
lDo not remove fuel hose from quick connector.
lKeep the original fuel hose to be free from intrusion of dust or foreign substances with a suitable cover.
4. Install the fuel pressure gauge as shown in the figure.
lWipe off oil or dirt from hose insertion part using cloth moist-
ened with gasoline.
lApply proper amount of gasoline between top of the fuel tube
and No.1 spool.
lInsert fuel hose for fuel pressure check until it touches the
No.1 spool on fuel tube.
lUse NISSAN genuine hose clamp (part number: 16439
N4710 or 16439 40U00).
lWhen reconnecting fuel line, always use new clamps.
lWhen reconnecting fuel hose, check the original fuel hose for
damage and abnormality.
lUse a torque driver to tighten clamps.
lInstall hose clamp to the position within 1 - 2 mm (0.04 - 0.08
in).
lMake sure that clamp screw does not contact adjacent parts.
5. 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.
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.
lDo not perform fuel pressure check with system operating. Fuel pressure gauge may indicate false
readings.
lDuring fuel pressure check, confirm for fuel leakage from fuel connection every 3 minutes.
9. If result is unsatisfactory, go to next step.
10. Check the following.
lFuel hoses and fuel tubes for clogging
lFuel filter for clogging
lFuel pump
lFuel 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,

Fuel FilterEBS0036N
DESCRIPTION
A water draining cock is on the lower side and a priming pump for bleeding air is on the upper side.
AIR BLEEDING
Pump the priming pump to bleed air.
lWhen air is bled completely, the pumping of the priming pump
suddenly becomes heavy. Stop the operation at that time.
lIf it is difficult to bleed air by the pumping of the priming pump
(the pumping of the priming pump does not become heavy), dis-
connect the fuel supply hose between the fuel filter and the fuel
gallery. Then, perform the operation described above, and make
sure that fuel comes out. (Use a pan, etc. so as not to spill fuel.
Do not let fuel get on engine and other parts.) After that, connect
the hose, then bleed air again.
lStart engine and let it idle for at least one minute after perform-
ing air bleeding.
WATER DRAINING
1. Remove the fuel filter, filter bracket, protector assembly from the dash panel as follows.
a. Remove the air cleaner case (upper), air duct assembly, and vacuum hose for brake booster (between the
vacuum pump and vacuum pipe).
CAUTION:
After the duct is removed, cover the opening with gum tape, etc. to prevent foreign object from
getting into the engine during the operation.
b. Remove the mounting nuts on the dash panel, then remove the fuel filter, filter bracket, and protector
assembly from the dash panel.
lIt is not necessary to disconnect the fuel hose.
2. Using a tool such as a pliers, loosen the water draining cock at the bottom of the fuel filter.
Accelerator Pedal Released Position LearningEBS009NW
DESCRIPTION
"Accelerator Pedal Released Position Learning" is an operating to learn the fully released position of the
accelerator pedal by monitoring the accelerator pedal position sensor output signal. It must be performed
when accelerator work unit or ECM is replaced.
OPERATION PROCEDURE
1. Turn ignition switch "ON".
2. Select "OFF ACCEL PO SIG" in "ACTIVE TEST" mode with
CONSULT-II
3. Make sure that accelerator pedal is released.
