6-1-4 ENGINE GENERAL INFORMATION AND DIAGNOSIS (H27 ENGINE)
When disconnecting couplers, don’t pull wire harness but
make sure to hold coupler itself. With lock type coupler, be
sure to unlock before disconnection. Attempt to disconnect
coupler without unlocking may result in damage to coupler.
When connecting lock type coupler, insert it till clicking
sound is heard and connect it securely.
Precaution on Fuel System Service
Work must be done with no smoking, in a well-ventilated area and away from any open flames.
As fuel feed line (between fuel pump and fuel pressure regulator) is still under high fuel pressure even after
engine was stopped, loosening or disconnecting fuel feed line directly may cause dangerous spout of fuel to
occur where loosened or disconnected. Before loosening or disconnecting fuel feed line, make sure to
release fuel pressure according to “FUEL PRESSURE RELIEF PROCEDURE” in this section.
A small amount of fuel may be released after the fuel line is disconnected.
In order to reduce the chance of personal injury, cover the fitting to be disconnected with a shop cloth. Put
that cloth in an approved container when disconnection is completed.
Never run engine with fuel pump relay disconnected when engine and exhaust system are hot.
Fuel or fuel vapor hose connection varies with each type of
pipe. When reconnecting fuel or fuel vapor hose, be sure to
connect and clamp each hose correctly referring to left fig-
ure.
After connecting, make sure that the hose has no twist or
kink.
When installing fuel union bolt gasket, always use new gas-
ket and tighten union bolt to specified torque according to
“TIGHTENING TORQUE SPECIFICATION” in Section 6C.
When installing injector, fuel feed pipe or fuel pressure regu-
lator, lubricate its O-ring with gasoline.
When connecting fuel pipe flare nut, first tighten flare nut by
hand and then tighten it to specified torque.
[A] : With short pipe, fit hose as far as it reaches pipe joint as shown.
[B] : With following type pipe, fit hose as far as its peripheral projection as shown.
[C] : With bent pipe, fit hose as far as its bent part as shown or till pipe is about 20
to 30 mm (0.79 – 1.18 in.) into the hose.
[D] : With straight pipe, fit hose till pipe is about 20 to 30 mm (0.79 – 1.18 in.) into
the hose.

2. Pipe
3. Clamp
“a” : Clamp securely at a position 3 to 7 mm (0.12 – 0.27 in.) from hose end.
“b” : 20 to 30 mm (0.79 – 1.18 in.)

6F2-6 IGNITION SYSTEM (FOR H27 ENGINE)
Ignition Spark Check
1) Remove surge tank cover.
2) Disconnect injector coupler (1).
3) Remove spark plug and check it for condition and type, refer-
ring to “SPARK PLUG” in this section.
4) If OK, connect ignition coil coupler to ignition coil assembly
and connect spark plug to ignition coil assembly. Ground
spark plug.
5) Crank engine and check if each spark plug sparks.
If no spark is emitted, inspect the related parts as described
under “DIAGNOSIS” in this section.
6) After checking, install spark plug, referring to “SPARK PLUG”
in this section.
7) Connect injector coupler (1).
8) Install surge tank cover.
Ignition Timing Check and Adjustment
1) Start engine and warm it up to normal operating tempera-
ture.
2) Make sure that all of electrical loads except ignition are
switched off.
3) Check to be sure that idle speed is within specification.
Refer to Section 6E2.
4) Connect SUZUKI scan tool to DLC (1) with ignition switch
OFF, restart engine and fix ignition timing by using fixed
spark mode of SUZUKI scan tool.
Special tool
(A) : SUZUKI scan tool WARNING:
Without disconnection of injector coupler, combustible
gas may come out from spark plug holes during this test
and may get ignited in engine room.
NOTE:
Before starting engine, place transmission gear shift
lever in “Neutral” (shift selector lever to “P” range for A/T
model), and set parking brake.
