2001 NISSAN ALMERA TINO fuel pump

Fuel Filter
DESCRIPTIONNLEC0623A water draining cock is on the lower side and a priming pump for
bleeding air is on the upper side.
SEF375Y
AIR BLEEDINGNLEC06241. 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 DRAININGNLEC0625+If the MI lights up (not flashes) during the engine operation,
drain the water as follows. (If fuel filter switch is equipped.)
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. 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.

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!(2.2 - 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
bracket, protector assembly in the reverse order of removal.
CAUTION:
Do not over-tighten the water draining cock. This will damage
the cock thread, resulting in water or fuel leak.
5. Bleed air of the fuel filter. Refer to EC-1094.
+Start engine and let it idle for at least one minute after
performing air bleeding.
6. Start the engine, then check that the MI goes off. (If fuel filter
switch is equipped.)

IntroductionNLEC0630The engine has an ECM to control major systems such as fuel
injection control, fuel injection timing control, glow control system,
etc. The ECM accepts input signals from sensors and instantly
drives electronic control fuel injection pump. It is essential that both
input and output signals are proper and stable. At the same time,
it is important that there are no problems such as vacuum leaks,
or other problems with the engine.
It is much more difficult to diagnose a problem that occurs intermit-
tently rather than continuously. Most intermittent problems are
caused by poor electric connections or improper wiring. In this
case, careful checking of suspected circuits may help prevent the
replacement of good parts.
A visual check only may not find the cause of the problems. A road
test with CONSULT-II or a circuit tester connected should be per-
formed. Follow the ªWork Flowº, EC-1109.
Before undertaking actual checks, take a few minutes to talk with
a customer who approaches with a driveability complaint. The cus-
tomer can supply good information about such problems, espe-
cially intermittent ones. Find out what symptoms are present and
under what conditions they occur. A ªDiagnostic Worksheetº like the
example on next page should be used.
Start your diagnosis by looking for ªconventionalº problems first.
This will help troubleshoot driveability problems on an electronically
controlled engine vehicle.

DIAGNOSTIC WORKSHEETNLEC0630S01There are many operating conditions that lead to the malfunction
of engine components. A good grasp of such conditions can make
troubleshooting faster and more accurate.
In general, each customer feels differently about a problem. It is
important to fully understand the symptoms or conditions for a
customer complaint.
Utilize a diagnostic worksheet like the one shown below in order to
organize all the information for troubleshooting.
