2. Install the fuel pressure gauge into the fuel line as shown in the
figure.
3. Turn ignition switch “ON”, and check for fuel leakage.
4. Start engine and check for fuel leakage.
5. Read the indication of fuel pressure gauge.
6. If result is unsatisfactory, go to next step.
7. 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.At idling:

BASIC SERVICE PROCEDURE
2. Perform “FUEL PRESSURE RELEASE” in “WORK SUPPORT”
mode with CONSULT-II.
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-II
1. Remove fuel pump fuse located in fuse box.
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
NOTE:
●When reconnecting fuel line, always use new clamps.
●Make sure that clamp screw does not contact adjacent parts.
●Use a torque driver to tighten clamps.
●Use Pressure Gauge to check fuel pressure.
1. Release fuel pressure to zero. Refer to EC-427, "
FUEL PRESSURE RELEASE" .
2. Install the fuel pressure gauge with the fuel pressure check
adapter as shown in the figure.
3. Turn ignition switch “ON”, and check for fuel leakage.
4. Start engine and check for fuel leakage.
5. Read the indication of fuel pressure gauge.
6. If result is unsatisfactory, go to next step.
7. 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.

DESCRIPTIONNJEC0623A water draining cock is on the lower side and a priming pump for
bleeding air is on the upper side.
SEF375Y
AIR BLEEDINGNJEC06241. After the repair, bleed air from the piping by pumping the prim-
ing pump up and down until it becomes heavy.
2. To start the engine, rotate the starter for a maximum of 30
seconds. To start the engine more quickly, crank the engine
while pumping the priming pump (requires two workers).
3. If the engine does not start after rotating the starter for a maxi-
mum of 30 seconds, stop it once, and pump the priming pump
again until it becomes heavy.
4. Rotate the starter again until the engine starts running.
5. After the engine starts, let it idle for at least 1 minute to stabi-
lize the behavior.
When air is bled completely, the pumping of the priming
pump suddenly becomes heavy. Stop the operation at that
time.
If it is difficult to bleed air by the pumping of the priming
pump (the pumping of the priming pump does not become
heavy), disconnect the fuel supply hose between the fuel
filter and the injection pump. 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.
Start engine and let it idle for at least one minute after
performing air bleeding.
WATER DRAININGNJEC06251. 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. Disconnect the water level warning sensor harness connector.
c. Remove the mounting nuts on the dash panel, then remove the
fuel filter, filter bracket, and protector assembly from the dash
panel.
It 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 water level warning sensor located under
the fuel filter.
BASIC SERVICE PROCEDUREYD
Fuel Filter
EC-32
3. Install the fuel filter, filter bracket, and protector assembly tem-
porarily. Then, drain the water by pumping the priming pump
with the filter standing straight.
Extend the drain hose if necessary.
Water amount when the MI lights up:
65 - 100 m(2.3 - 3.5 Imp fl oz)
CAUTION:
When the water is drained, the fuel is also drained. Use a pan,
etc. to avoid fuel adherence to the rubber parts such as the
engine mount insulator.
4. Tighten the water draining cock, then install the fuel filter, filter
