GENERAL DESCRIPTION
The main components of the fuel system are fuel tank, fuel pump assembly (with fuel filter, fuel level gauge, fuel
pressure regulator and tank pressure control valve), fuel/vapor separator fuel feed line and fuel vapor line.
For the details of fuel flow and fuel vapor flow, refer to “GENERAL DESCRIPTION” in Section 6E. WARNING:
For vehicles equipped with Supplemental Restraint (Air Bag) System:
Service on and around the air bag system components or wiring must be performed only by an
authorized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under
“General Description” in air bag system section in order to confirm whether you are performing ser-
vice on or near the air bag system components or wiring. Please observe all WARNINGS and “Ser-
vice Precautions” under “On-Vehicle Service” in air bag system section before performing service
on or around the air bag system components or wiring. Failure to follow WARNINGS could result in
unintentional activation of the system or could render the system inoperative. Either of these two
conditions may result in severe injury.
Technical service work must be started at least 90 seconds after the ignition switch is turned to the
“LOCK” position and the negative cable is disconnected from the battery. Otherwise, the system
may be activated by reserve energy in the Sensing and Diagnostic Module (SDM).
CAUTION:
The engine of this vehicle requires the use of unleaded fuel only. Use of leaded and/or low lead fuel
can result in engine damage and reduce the effectiveness of the emission control system.

3) Remove fuel pump assembly (1) from fuel tank (2).
INSPECTION
Check fuel pump assembly for damage.
Check fuel suction filter (1) for evidence of dirt and contami-
nation.
If present, replace or clean and check for presence of dirt in
fuel tank.
For operation or electrical circuit inspection by referring to
Section 6E1.
For inspection of fuel level gauge (2) by referring to Section
8.
Check tank pressure control valve referring to the following
procedures.
a) Air should pass through valve (2) smoothly from fuel vapor
line hose (3) “A” to “B” when blown hard.
b) Also, when vacuum pump (4) is connected to fuel vapor
hose and pump air through valve, air should pass from “B”
to “A”.
Special tool
(A) : 09917-47910
If air doesn’t pass through valve in Step a) or vacuum is main-
tained in Step b), replace fuel filter assembly (1).

WARNING:
Do not such air through fuel vapor line hose. Fuel vapor
inside valve is harmful.12

ENGINE AND EMISSION CONTROL SYSTEM 6E1-5
AIR INTAKE SYSTEM
The main components of the air intake system are air cleaner (1), air cleaner outlet hose (2), throttle body (3),
idle air control valve (4) and intake manifold (5).
The air (by the amount corresponding to the throttle valve (6) opening and engine speed) is filtered by the air
cleaner (1), passes through the throttle body (3), is distributed by the intake manifold (5) and finally drawn into
each combustion chamber.
When the idle air control valve (4) is opened according to the signal from ECM, the air (7) bypasses the throttle
valve (6) through bypass passage and is finally drawn into the intake manifold (5).
