5.CHECK FUEL INJECTORS
1. Stop engine and then turn ignition switch ON.
2. Check voltage between ECM terminals 21, 22, 23, 40, 41, 42, 44, 63 and ground with CONSULT-III or tester.
Refer to Wiring Diagram for fuel injectors, EC-1150
.

6.CHECK FUNCTION OF IGNITION COIL-I
CAUTION:
Do the following procedure in the place where ventilation is good without the combustible.
1. Turn ignition switch OFF.
2. Remove fuel pump fuse in IPDM E/R to release fuel pressure.
NOTE:
Do not use CONSULT-III to release fuel pressure, or fuel pres-
sure applies again during the following procedure.
3. Start engine.
4. After engine stalls, crank it two or three times to release all fuel
pressure.
5. Turn ignition switch OFF.
6. Remove all ignition coil harness connectors to avoid the electri- cal discharge from the ignition coils.
7. Remove ignition coil and spark plug of the cylinder to be checked.
8. Crank engine for five seconds or more to remove combustion gas in the cylinder.
9. Connect spark plug and harness connector to ignition coil.
10. Fix ignition coil using a rope etc. with gap of 13 - 17 mm between the edge of the spark plug and grounded metal portion
as shown in the figure.
11. Crank engine for about three seconds, and check whether spark
is generated between the spark plug and the grounded metal
portion.
CAUTION:
Do not approach to the spar k plug and the ignition coil
within 50cm. Be careful not to get an electrical shock
while checking, because the el ectrical discharge voltage
becomes 20kV or more.
It might cause to damage the ignition coil if the gap of more than 17 mm is taken.
NOTE:
When the gap is less than 13 mm, the spark might be generated even if the coil is malfunctioning.

Checking Drive BeltsINFOID:0000000001429496
WARNING:
Be sure to perform when engine is stopped.
1. Inspect belts for cracks, fraying,
wear and oil. If necessary, replace.
2. Inspect drive belt deflection or tension at a point on belt midway between pulleys.
Inspection should be done only when engine is cold, or over30 minutes after engine is stopped.
Measure the belt tension with belt tension gauge (Commercial service tool: BT3373-F or equivalent) (A) at points marked
shown in the figure.
When measuring the deflection, apply 98 N (10 kg, 22 lb) at
the marked point.
Adjust if the belt deflection exc eeds the limit or if the belt ten-
sion is not within specifications.
CAUTION:
• When checking the belt deflect ion or the tension immedi-
ately after installation, first ad just it to the specified value.
Then, after turning crankshaft two turns or more, re-adjust
to the specified value to avo id variation in deflection
between pulleys.
Tighten idler pulley lock nut by hand and measure the deflection or the tension without loose-
ness.
Belt Deflection and Tension
*: If belt tension gauge cannot be installed at check points shown, check drive belt tension at different location on belt.

When belt is replaced with a new one, adjust it
to value for “New belt” to accommodate for insuffi-
cient adaptability with pulley grooves.
When deflection or tension of belt being used exceeds “Limit”, adjust it to value for “After adjust-
ment”.
When checking belt deflection or tension immediately af ter installation, first adjust it to the specified
value. Then, after turning crankshaft two turns or mo re, re-adjust to the specified value to avoid vari-
ation in deflection between pulleys.
When installing belt, make sure that it is correctly engaged with pulley grooves.
Keep engine oil, working fl uid and engine coolant away from belt and pulley grooves.
Do not twist or bend belt excessively.
ALTERNATOR AND POWER STEERING OIL PUMP BELT
1. Remove front engine undercover with power tool.
2. Loosen idler pulley lock nut (A ) and adjust tension by turning

3. Remove A/C compressor belt. Refer to EM-14, "
Tension Adjustment".
CAUTION:
Grease is applied to idler pulley adjusting bol t. Be careful to keep grease away from belt.
INSTALLATION
1. Install belts to pulley in reverse order of removal.

Make sure that O-ring and its mating
part are free of foreign material.
When installing O-ring, be careful not to scratch it with tool or fingernails. Also be careful not
to twist or stretch O-ring. If O-ring was stretc hed while it was being attached, do not insert it
quickly into fuel tube.
Insert new O-ring straight into fuel tube. Do not decenter or twist it.
Insert fuel damper and fuel sub- tube straight into fuel tube.
Tighten mounting bolts evenly in turn.
After tightening mounting bolts, make sure that there is no gap between flange and fuel tube.
2. Install new O-rings to fuel injector, paying attention to the following. CAUTION:
Upper and lower O-ring are different. Be careful not to confuse them.
Handle O-ring with bare hands. Do not wear gloves.
Lubricate O-ring with new engine oil.
Do not clean O-ring with solvent.
Make sure that O-ring and its mating part are free of foreign material.
When installing O-ring, be careful not to scratch it with tool or fingernails. Also be careful not to
twist or stretch O-ring. If O-ring was stretc hed while it was being attached, do not insert it
quickly into fuel tube.
Insert O-ring straight into fuel in jector. Do not decenter or twist it.
3. Install fuel injector to fuel tube as follows:
a. Insert clip into clip mounting groove on fuel injector. Insert clip so that protrusion “A ” of fuel injector matches cutout
“A” of clip.
CAUTION:
Do not reuse clip. Replace it with a new one.
Be careful to keep clip from interfering with O-ring. If interference occurs, replace O-ring.
b. Insert fuel injector into fuel tube with clip attached. Insert it while matching it to the axial center.
Insert fuel injector so that protrusion “B” of fuel tube matches
cutout “B” of clip.
Make sure that fuel tube flange is securely fixed in flange fixing groove on clip.
c. Make sure that installation is complete by checking that fuel injector does not rotate or come off.
Make sure that protrusions of fuel injectors are aligned withcutouts of clips after installation.
4. Install spacers on intake manifold.
5. Install fuel tube and fuel injector assembly to intake manifold. CAUTION:
Be careful not to let tip of injector nozzle come in contact with other parts.
Fuel tube side : Blue
Nozzle side : Brown

9. Install crankshaft pulley as follows:
a. Fix crankshaft using the ring gear stopper [SST: KV10117700 (J44716)].
b. Install crankshaft pulley, taking care not to damage front oil seal. When press-fitting crankshaft pulley with plastic hamme r, tap on its center portion (not circumference).
c. Tighten crankshaft pulley bolt.
d. Put a paint mark on crankshaft pulley aligning with angle mark on crankshaft pulley bolt.
e. Further tighten by 90 degrees. (Angle tightening) Check the tightening angle by referencing to the notches. The
angle between two notches is 90 degrees.
10. Rotate crankshaft pulley in normal direction (clock wise when viewed from front) to confirm it turns
smoothly.
11. For the following operations, perform steps in the reverse order of removal. NOTE:
If hydraulic pressure inside chain tensioner drops after removal/installation, slack in the guide may gener-
ate a pounding noise during and just after engine start. However, this is normal. Noise will stop after
hydraulic pressure rises.
INSPECTION AFTER INSTALLATION
Inspection for Leaks
The followings are procedures for checking fluids leak, lubricates leak. Before starting engine, check oil/fluid levels incl uding engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to GI-44, "
Recommended Chemical Product and Sealant".
Use procedure below to check for fuel leakage.
- Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leak-
age at connection points.
- Start engine. With engine speed increased, che ck again for fuel leakage at connection points.
Run engine to check for unusual noise and vibration.
NOTE:
If hydraulic pressure inside chain tensioner drops af ter removal/installation, slack in guide may generate a
pounding noise during and just after the engine start. However, this does not indicate an unusualness. Noise
will stop after hydraulic pressure rises.
Warm up engine thoroughly to make sure there is no leakage of fuel, or any oil/fluids including engine oil and engine coolant.
