Troubleshooting
WARNING!
Keep hands, tools, and clothing away from radiator cooling fan to help prevent personal injury. This
fan is electric and can come on whether or not the engine is running. The fan can start automatically in
response to the ECT sensor with the ignition switch at the “ON” position.
NOTE
• Before performed trouble shooting, be sure to read the “Precautions of ECM Circuit Inspection”.
• When measuring circuit voltage, resistance and/or pulse signal at ECM connector, connect the
special tool to ECM and/or the ECM connectors referring to “Inspection of ECM and Its Circuits”.

General Description
Fuel System DescriptionS6RW0D1701001
CAUTION!
This engine requires the unleaded fuel only.
The leaded and/or low lead fuel can result in
engine damage and reduce the effectiveness
of the emission control system.
The main components of the fuel system are fuel tank,
fuel pump assembly (with fuel filter, fuel level gauge, fuel
pressure regulator), fuel feed line and fuel vapor line.
For the details of fuel flow, refer to “Fuel Delivery System
Diagram”.
Fuel Delivery System DescriptionS6RW0D1701002
The fuel delivery system consists of the fuel tank, fuel
pump assembly (with built-in fuel filter and fuel pressure
regulator), delivery pipe, injectors and fuel feed line.
The fuel in the fuel tank is pumped up by the fuel pump,
sent into delivery pipe and injected by the injectors.
As the fuel pump assembly is equipped with built-in fuel
filter and fuel pressure regulator, the fuel is filtered and
its pressure is regulated before being sent to the feed
pipe.
The excess fuel at fuel pressure regulation process is
returned back into the fuel tank.
Also, fuel vapor generated in fuel tank is led through the
fuel vapor line into the EVAP canister.
For system diagram, refer to “Fuel Delivery System
Diagram”.
Fuel Pump DescriptionS6RW0D1701003
The fuel pump (1) is an in-tank type electric pump.
Incorporated in the pump assembly are;
a fuel filter (2), a fuel pressure regulator (3) and a fuel
level sensor (gauge) (4).

Fuel Pressure InspectionS6RW0D1704001
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.
1) Relieve fuel pressure in fuel feed line referring to
“Fuel Pressure Relief Procedure”.
2) Disconnect fuel feed hose from fuel delivery pipe.
3) Connect special tools and hose between fuel feed
hose (1) and fuel delivery pipe as shown in figure,
and clamp hoses securely in order to ensure that no
leaks occur during checking.

Diagnostic Information and Procedures
Cranking System Symptom DiagnosisS6RW0D1904001
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
