INSTALLATION
For installation, reverse removal procedure and note the follow-
ings.
•Use new O-ring.
•Apply thin coat of gasoline to O-ring to facilitate installation.
•Tighten fuel pressure regulator (1) bolts to specified torque.
Tightening torque
Fuel pressure regulator bolt
(a) : 10 N·m (1.0 kg-m, 7.5 lb-ft)
•With engine “OFF” and ignition switch “ON”, check for fuel
leaks around fuel line connection.
Fuel injector
ON-VEHICLE INSPECTION
1) Using sound scope (1) or such, check operating sound of
injector when engine is running or cranking.
Cycle of operating sound should vary according to engine
speed.
If no sound or an unusual sound is heard, check injector cir-
cuit (wire or coupler) or injector.
2) Disconnect connector from injector, connect ohmmeter
between terminals of injector and check resistance.
If resistance is out of specification, replace.
Fuel injector resistance:
14.2 – 14.8 Ω
Ω Ω Ω (at 20°C, 68°F)
3) Connect connector to injector securely.

(a) : 30 N·m (3.0 kg-m, 22.0 lb-ft)
7) Connect vacuum hose (5) and fuel return hose (4) to fuel
pressure regulator.
8) Connect fuel feed hose (1) and fuel return hose (2).
9) Connect connectors of injector wire (3) to injectors.
10) Install throttle body and intake collector, refer to “THROTTLE
BODY” in this section.
11) With engine “OFF” and ignition switch “ON”, check for fuel
leaks around fuel line connection.

5) Set timing light to ignition harness for No.1 cylinder.
6) Using timing light, check that timing observed from viewpoint
is within specification.
Initial ignition timing of viewpoint
(when it is fixed by SUZUKI scan tool) :
5 ± 1° BTDC
Ignition order :
1-6-5-4-3-2
Special tool
(A) : 09930-76420
7) If ignition timing is out of specification, loosen flange bolt,
adjust timing by turning CMP sensor (1) while engine is run-
ning, and then tighten bolt (2).
Tightening torque
CMP sensor bolt (a) : 15 N·m (1.5 kg-m, 11.0 lb-ft)
8) After tightening bolt (2), recheck that ignition timing is within
specification.
9) After checking and/or adjusting, end fixed spark mode of
SUZUKI scan tool.
10) With engine idling (closed throttle position and vehicle
stopped), check that ignition timing is about BTDC 12-16°
(shown in the figure). Also, check that increasing engine
speed advances ignition timing.
If above check results are not satisfactory, check input sig-
nals related to this system.

NOTE:
In this state, ignition timing may vary more or less of ini-
tial ignition timing but it is nothing abnormal.

INSPECTION
Inspect them for electrode wear, carbon deposits and Insulator
damage.
If any abnormality is found, replace them with specified new plug.
Spark plug air gap “a” :
1.0 – 1.1 mm (0.039 – 0.043 in.)
Spark plug type :
DENSO K20PR-U11/SK16PR11
NGK BKR6E-11/*IFR5J11
INSTALLATION
1) Install spark plug (3) and tighten them to specified torque.
Tightening torque
Spark plug (a) : 25 N·m (2.5 kg-m, 18.0 lb-ft)
2) Install ignition coil assembly (2) securely.
3) Tighten ignition coil bolt (1), and then connect ignition coil
coupler.
4) Install ignition coil cover.CAUTION:
When servicing the iridium/platinum spark plugs (slender
center electrode type plugs), do not touch the center
electrode to avoid damage to it. The electrode is not
strong enough against mechanical force as it is slender
and its material is not mechanically tough.
NOTE:
Under –25°C (–13°F), it is highly recommended to use the
spark plugs with an asterisk (*) for better engine starting
performance.

2) Install CMP sensor to camshaft.
Fit the dog of CMP sensor coupling into the slots of cam-
shaft, when installing. The dogs of CMP sensor coupling are
offset. Therefore, if the dogs can not be fitted into the slots,
turn the CMP sensor shaft by 180 degree and try again.
3) Tighten CMP sensor bolt (3).
Tightening torque
CMP sensor bolt (a) : 15 N·m (1.5 kg-m, 11.0 lb-ft)
4) Connect CMP sensor coupler (2) to CMP sensor (1).
5) Install A/T fluid level gauge and filler tube.
