the starter contacts (magnet switch) turns ON and
the starter motor starts turning over.TROUBLESHOOTING HINTS
1. Starter motor does not turn over at all.
DCheck starter (coil).
DCheck battery terminals for proper contact.
2. Starter motor does not stop rotating.
DCheck starter (magnet switch).

12. Install the ignition coils and spark plugs.
13. Use the MUT-IIto erase the self-diagnosis codes or
disconnect the battery cable from the battery ( - ) terminal
for 10 seconds or more and then reconnect the cable.
NOTE
This will erase the diagnosis code resulting from the crank
angle sensor connector being disconnected.
MANIFOLD VACUUM CHECK
1. Set the vehicle to the pre-inspection condition.
2. Turn the ignition switch to the “LOCK” (OFF) position.
3. Set the engine tachometer or connect the MUT-II.
4. Check that the idle speed is within the standard value.
NOTE
When using the MUT-II, select the code No.22.
5. Connect the three-way union joint to the vacuum hose
between the fuel pressure control valve and the air intake
plenum, and connect a vacuum gauge.
6. Check the manifold vacuum at idle.
Limit: 58 kPa
7. Turn the ignition switch to the “LOCK” (OFF) position.
8. Remove the vacuum gauge and install the vacuum hose
in its original location.
9. Remove the engine tachometer or the MUT-II.
LASH ADJUSTER CHECK
If an abnormal noise (knocking) that seems to be coming
from the lash adjuster is heard after starting the engine and
does not stop, carry out the following check.
NOTE
(1) The abnormal noise which is caused by a problem
with the lash adjusters is generated after the engine
is started, and will vary according to the engine speed.
However, this noise is not related to the actual engine
load.
Because of this, if the noise does not occur
immediately after the engine is started, if it does not
change in accordance with the engine speed, or if
it changes in accordance with the engine load, the
source of the noise is not the lash adjusters.

PROBLEM SYMPTOMS TABLE (FOR YOUR INFORMATION)
ItemsSymptom
StartingWon’t startThe starter is used to crank the engine, but there is no combustion within the
cylinders, and the engine won’t start.
Fires up and diesThere is combustion within the cylinders, but then the engine soon stalls.
Hard startingEngine starts after cranking a while.
Idling
stability
HuntingEngine speed doesn’t remain constant; changes at idle.
stability
Rough idleUsually, a judgement can be based upon the movement of the tachometer
pointer, and the vibration transmitted to the steering wheel, shift lever, body, etc.
This is called rough idle.
Incorrect idle speedThe engine doesn’t idle at the usual correct speed.
Engine stall
(Die out)The engine stalls when the foot is taken from the accelerator pedal, regardless
of whether the vehicles is moving or not.
Engine stall
(Pass out)The engine stalls when the accelerator pedal is depressed or while it is being
used.
DrivingHesitation Sag“Hesitation” is the delay in response of the vehicle speed (engine speed) that
occurs when the accelerator is depressed in order to accelerate from the speed
at which the vehicle is now traveling, or a temporary drop in vehicle speed
(engine speed) during such acceleration.
Serious hesitation is called “sag”. (Refer to Fig. 1)
Poor accelerationPoor acceleration is inability to obtain an acceleration corresponding to the
degree of throttle opening, even though acceleration is smooth, or the inability
to reach maximum speed.
StumbleEngine speed increase is delayed when the accelerator pedal is initially
depressed for acceleration. (Refer to Fig. 2)
ShockThe feeling of a comparatively large impact or vibration when the engine is
accelerated or decelerated.
SurgeThis is repeated surging ahead during constant speed travel or during variable
speed travel.
KnockingA sharp sound like a hammer striking the cylinder walls during driving and which
adversely affects driving.
StoppingRun on
(“Dieseling”)The condition in which the engine continues to run after the ignition switch is
turned to “LOCK” (OFF) position. Also called “Dieseling”.

FUEL PUMP CONNECTOR DISCONNECTION
(HOW TO REDUCE THE FUEL PRESSURE)
When removing the fuel pipe, hose, etc., since fuel pressure
in the fuel pipe line is high, do the following operation so
as to release the fuel pressure in the line and prevent fuel
from running out.
1. Remove the rear seat assembly. (Refer to GROUP 52A.)
2. Remove the protector.
3. Disconnect the fuel pump module connector.
4. After starting the engine and letting it run until it stops
naturally, turn the ignition switch to “LOOK” (OFF) position.
5. Connect the fuel pump module connector.
6. Install the protector and rear seat assembly.
(Refer to GROUP 52A.)
FUEL PUMP OPERATION CHECK
1. Check the operation of the fuel pump by using the MUT-II
to force-drive the fuel pump.
2. If the fuel pump will not operate, check by using the
following procedure, and if it is normal, check the drive
circuit.
(1) Turn the ignition switch to “LOOK” (OFF) position.
(2) Remove the rear seat assembly. (Refer to GROUP
52A.)
(3) Remove the protector.
(4) Disconnect the fuel pump module connector.
(5) When the fuel pump drive connector is attached
directly to the battery, check if the sound of the fuel
pump operation can be heard.
NOTE
As the fuel pump is an in-tank type, the fuel pump
sound is hard to hear, so remove the fuel filler cap
and check from the tank inlet.
(6) Check the fuel pressure by pinching the fuel hose
with the fingertips.
(7) Connect the fuel pump module connector.
(8) Install the protector and rear seat assembly. (Refer
to GROUP 52A.)

4. Connect the MUT-IIto the diagnosis connector.
5. Turn the ignition switch to “ON” position. (But do not start
the engine.)
6. Select “Item No. 07” from the MUT-IIActuator test to
drive the fuel pump.
7. Activate the injector and check the atomized spray
condition of the fuel.
The condition can be considered satisfactory unless it
is extremely poor.
8. Stop the actuation of the injector, and check for leakage
from the injector’s nozzle.
Standard value: 1 drop or less per minute
9. Activate the injector without activating the fuel pump; then,
when the spray emission of fuel from the injector stops,
disconnect the special tool and restore it to its original
condition.
10. Disconnect the MUT-II.
