DTC P0300 - P0304 NO.4-1CYLINDER MISFIRE, MULTIPLE CYLINDER
MISFIRE
SR20DE
Diagnostic Procedure (Cont'd)
EC-813

SAT652J
+If MI illuminates or blinks irregularly when engine is
running, water may have accumulated in fuel filter. Drain
water from fuel filter. If this does not correct the problem,
perform specified trouble diagnostic procedures.
+After performing each TROUBLE DIAGNOSIS, perform
ªDTC Confirmation Procedureº or ªOverall Function
Checkº.
The DTC should not be displayed in the ª DTC Confirma-
tion Procedureº if the repair is completed. The ªOverall
Function Checkº should be a good result if the repair is
completed.
SEF348N
+When measuring ECM signals with a circuit tester, never
allow the two tester probes to contact.
Accidental contact of probes will cause a short circuit and
damage the ECM power transistor.
+Do not use ECM ground terminals when measuring input/
output voltage. Doing so may result in damage to the
ECM's transistor. Use a ground other than ECM terminals,
such as the ground.
+Install the break-out box between ECM and ECM harness
connectors when measuring ECM input/output voltage.
SEF437Y
+Do not disconnect electronic control fuel injection pump
harness connector with engine running.
+Do not disassemble electronic control fuel injection pump.
If NG, take proper action.
+Do not disassemble injection nozzle.
If NG, replace injection nozzle.
+Even a slight leak in the air intake system can cause seri-
ous problems.
+Do not shock or jar the crankshaft position sensor (TDC).
SEF709Y
+Do not depress accelerator pedal when starting.
+Immediately after starting, do not rev up engine unneces-
sarily.
+Do not rev up engine just prior to shutdown.

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.)
