Fuel Tank Removal and InstallationS7RS0B1706013
WARNING!
Before starting the following procedure, be
sure to observe “Precautions on Fuel System
Service” in order to reduce the risk or fire
and personal injury.
Removal1) Relieve fuel pressure in fuel feed line according to
“Fuel Pressure Relief Procedure”.
2) Disconnect negative cable at battery.
3) Hoist vehicle.
4) Remove exhaust center pipe.
5) Disconnect fuel filler hose and breather hose from
filler neck referring to “Fue l Tank Inlet Valve Removal
and Installation”.
6) Due to absence of fuel tank drain plug, drain fuel tank by pumping fuel out through fuel tank filler.
Use hand operated pump device to drain fuel tank.
CAUTION!
• Do not force pump hose into fuel tank, or pump hose may damage fuel tank inlet
valve.
• Never store fuel in an open container due to possibility of fire or explosion.
7) Disconnect fuel pipe joint and fuel hoses (1) from fuel pipes (2) referring to “Fuel Hose Disconnecting
and Reconnecting”.
8) Support fuel tank (1) with jack (2) and remove its mounting bolts.
9) Lower fuel tank a little as to disconnect wire harness at connector (1) and ground wire (2), then remove
fuel tank.

Installation
CAUTION!
• When connecting joint, clean outside surfaces of pipe where joint is to be
inserted, push joint into pipe till joint lock
clicks and check to ensure that pipes are
connected securely, or fuel leak may
occur.
• Never let the fuel hoses touch the ABS sensor harness (if equipped).
1) If parts have been removed from fuel tank, install them before installing fuel tank to vehicle.
2) Raise fuel tank (1) with jack (2) and connect fuel pump connector (3), ground wire (4) and clamp wire
harness.

8) With engine OFF, turn ignition switch to ON position and check for fuel leaks.
Fuel Tank InspectionS7RS0B1706014
After removing fuel tank, check hoses and pipes
connected to fuel tank for leaks, loose connections,
deterioration or damage. Also check fuel pump
assembly gaskets for leaks, visually inspect fuel tank for
leaks and damage.
Replace any damaged or malconditioned parts.

Measure secondary coil for resistance.
If resistance is out of specification, replace ignition coil
assembly.
Secondary coil resistance
7.5 – 10.3 k Ω at 20 °C, 68 ° F
Ignition Timing InspectionS7RS0B1806007
NOTE
• Ignition timing is not adjustable. If ignition
timing is out of specification, check
system related parts.
• Before starting engine, place transmission gear shift lever in “Neutral” (shift selector
lever to “P” range for A/T model), and set
parking brake.
1) Connect scan tool to DLC (1) with ignition switch OFF.
Special tool
(A): SUZUKI scan tool
2) Start engine and warm it up to normal operating temperature.
3) Make sure that all of electrical loads except ignition are switched off.
4) Check to be sure that idle speed is within specification referring to “Idle Speed and IAC
Throttle Valve Opening Inspection in Section 1A”
5) Fix ignition timing by using “Fixed Spark” of “Misc Test” mode on scan tool.

6) Set timing light (1) to high-tension cord for No.1 cylinder and check that ignition timing is within
specification.
Initial ignition timing
Fixed with SUZUKI scan tool: 5 ± 3° BTDC (at
specified idle speed)
Ignition order
1 – 3 – 4 – 2
Special tool
(A): 09930–76420 7) If ignition timing is out
of specification, check the
followings.
• CKP sensor
• CKP sensor plate
• CMP sensor
• CMP sensor rotor tooth of camshaft
• VSS
• Timing chain cover installation
8) After checking initial igniti on timing, release ignition
timing fixation by using scan tool.
9) With engine idling (throttl e opening at closed position
and vehicle stopped), check that ignition timing is
about 3 ° – 13° BTDC. (Constant variation within a
few degrees from 3 ° – 13° BTDC indicates no
abnormality but proves operation of electronic timing
control system.) Also, check that increasing engine
speed advances ignition timing.
If the check results are not satisfactory, check CKP
sensor and ECM.

Diagnostic Information and Procedures
Cranking System Symptom DiagnosisS7RS0B1904001
Possible symptoms due to starting system trouble would be as follows:
• Starting motor does not run (or runs slowly)
• Starting motor runs but fails to crank engine
• Abnormal noise is heard
Proper diagnosis must be made to determine exactly where the cause of each trouble lies in battery, wiring harness,
(including starting motor switch), starting motor or engine.
Do not remove motor just because starting motor does not run. Check the following items and narrow down scope of
possible causes.
1) Condition of trouble
2) Tightness of battery terminals (including ground cable connection on engine side) and starting motor terminals
3) Discharge of battery
4) Mounting of starting motor
