Precautions
Precautions on Fuel System ServiceS6RW0D1700001
WARNING!
Before attempting service of any type on fuel system, the following should be always observed in
order to reduce the risk of fire and personal injury.
• Disconnect negative cable at battery.
• Do not smoke, and place no smoking signs near work area.
• Be sure to have CO
2 fire extinguisher handy.
• Be sure to perform work in a well-ventilated area and away from any open flames (such as gas hot
heater).
• Wear safety glasses.
• To relieve fuel vapor pressure in fuel tank, remove fuel filler cap from fuel filler neck and then
reinstall it.
• As fuel feed line is still under high fuel pressure even after stopping engine, loosening or
disconnecting fuel feed line directly may cause dangerous spout of fuel. Before loosening or
disconnecting fuel feed line, make sure to relieve fuel pressure referring to “Fuel Pressure Relief
Procedure”.
• A small amount of fuel may be released when the fuel line is disconnected. In order to reduce the
risk of personal injury, cover a shop cloth to the fitting to be disconnected. Be sure to put that cloth
in an approved container after disconnecting.
• Never run engine with fuel pump relay disconnected when engine and exhaust system are hot.
• Note that fuel hose connection varies with each type of pipe. Be sure to connect and clamp each
hose correctly referring to “Fuel Hose Disconnecting and Reconnecting”.
After connecting, make sure that it has no twist or kink.
• When installing injector or fuel feed pipe, lubricate its O-ring with gasoline.
• When servicing the fuel tank, it should be treated with respect, with no contact with sharp edges or
hot surfaces. In addition, the fuel tank should not be dropped since fuel tank, fuel pump and other
components can be damaged by the impact. If dropped, all components should be replaced because
there is a risk of damage.
• The fuel tank is made of resin.
Be sure not to allow solvent (chemical article such as grease and sealant) to attach to the fuel tank
as some chemical reaction may occur, causing the fuel tank to be swollen, hardened or distorted
leakage and resulting in fuel leakage from the fuel tank.

Installation
Reverse removal procedure for installation noting the
following.
• Replace injector O-ring (1) with new one using care
not to damage it.
• Check if cushion (2) is scored or damaged. If it is,
replace with new one.
• Apply thin coat of fuel to O-rings (1), and then install
injectors (3) into delivery pipe (4) and cylinder head.
Make sure that injectors rotate smoothly (6). If not,
probable cause is incorrect installation of O-ring.
Replace O-ring with new one.
• Tighten delivery pipe bolts (5) to specified torque and
make sure that injectors rotate smoothly.
Tightening torque
Fuel delivery pipe bolt (a): 25 N·m (2.5 kgf-m, 18.0
lb-ft)
• After installation, with engine OFF and ignition switch
ON, check for fuel leaks around fuel line connection.Fuel Injector InspectionS6RW0D1706009
WARNING!
• Before starting the following procedure, be
sure to observe “Precautions on Fuel
System Service” in order to reduce the risk
of fire and personal injury.
• Put injector and battery as far away as
possible in order to reduce risk of fire and
personal injury when connecting/
disconnecting test lead to/from battery.

1) Relieve fuel pressure according to “Fuel Pressure
Relief Procedure” if equipped.
2) Disconnect fuel feed hose from delivery pipe.
3) Set special tools as follows.
Special tool
(A): 09912–58421
(B): 09930–88530
(C): 09912–57610
a) Fit washer (1) (inside diameter 13.5 – 14.5
mm(0.532 – 0.570 in.)) to injector (2), and then
install injector to special tool (A).
b) Connect special tool (B) to injector.
c) Install special tool (C) to special tool (A).
d) Connect fuel feed hose to special tool (A).

4) Install suitable vinyl tube onto injector nozzle to
prevent fuel from splashing out when injecting.
5) Put graduated cylinder under injector.
6) Operate fuel pump and apply fuel pressure to
injector as follows:
a) When using scan tool:
i) Connect scan tool to DLC with ignition switch
OFF.
ii) Turn ignition switch ON, clear DTC and
select “MISC TEST” mode on scan tool.
iii) Turn fuel pump ON by using scan tool.
Special tool
(A): SUZUKI scan tool (SUZUKI-SDT)
b) When not using scan tool:
i) Remove fuel pump relay from connector.
ii) Connect two terminals of relay connector
using service wire (1) as shown in figure.
CAUTION!
Check to make sure that connection is made
between correct terminals. Wrong
connection can cause damage to ECM, wire
harness, etc.

iii) Turn ignition switch ON.7) Apply battery voltage to injector (1) for 15 seconds
and measure injected fuel volume with graduated
cylinder. Test each injector two or three times. If
injected volume is out of reference value greatly,
replace injector.
Reference injected fuel volume
Approx. 46 cc/15 sec. (1.62/1.55 US/lmp oz/15
sec.)
8) Check fuel leakage from injector nozzle. Do not
operate injector for this check (but fuel pump should
be at work). If fuel leaks (1) more than the following
specifications, replace.
Fuel leakage
Less than 1 drop/min.
9) Remove injector from special tool (A) and disconnect
special tool (B) from injector.
WARNING!
As fuel feed line is still under high fuel
pressure even after inspection, removing
injector directly may cause dangerous spout
of fuel. Before removing injector, make sure
to relieve fuel pressure as follows.
1. Stop operation of fuel pump.
2. Put graduated cylinder under injector.
3. Apply battery voltage to injector until no
fuel is injected from injector.

10) Carry out Steps 3) through 9) on each injector to
obtain 4 readings.
11) After checking, disconnect fuel feed hose from
special tool (A) and remove special tool (B).
12) Connect fuel feed hose to delivery pipe.
