1.  Remove the 2nd seat (Refer to "BD" group in this SERVICE MANUAL).
2.  Open the carpet for fuel pump and remove the service cover for 
     fuel pump (A).

1. PREPARING

1.  Disconnect the fuel pump connector (A).     
2.  Start the engine and wait until fuel in fuel line is exhausted.
3.  After the engine stalls, turn the ignition switch to OFF position 

and disconnect the negative (-) terminal from the battery.

2. RELEASE THE INTERNAL PRESSURE

Be sure to reduce the fuel pressure before disconnecting the fuel feed 
hose, otherwise fuel will spill out.

NOTE

1.  Disconnect the fuel feed hose from the delivery pipe.

2.  Install the Fuel Pressure Gage Adapter (09353-38000) between the delivery pipe and the fuel feed hose.
3.  Connect the Fuel Pressure Gage Connector (09353-24000) to the Fuel Pressure Gage Adapter (09353-38000).
4.  Connect the Fuel Pressure Gage and Hose (09353-24100) to Fuel Pressure Gage Connector (09353-24000).
5.  Connect the fuel feed hose to the Fuel Pressure Gage Adapter (09353-38000).

3. INSTALL THE SPECIAL SERVICE TOOL (SST) FOR MEASURING THE FUEL PRESSURE

Cover the hose connection with a shop towel to prevent splashing of fuel caused by residual pressure in the fuel line.

Fuel Pressure Regulator

Condition

Suspected Area

Fuel Pressure Regulator

Fuel filter

Fuel leak on the fuel-pressure
regulator that is assembled 
on fuel pump because of poor 
seating of the fuel-pressure 
regulator.

Clogged fuel filter

Sticking fuel pressure 
regulator

Probable Cause

Fuel Pressure too low

Fuel Pressure too High

1.  Diconnect the negative (-) terminal from the battery.
2.  Connect the fuel pump connector.
3.  Connect the battery negative (-) terminal.
4.  Start the engine and measure the fuel pressure at idle.

 

Standard Value: 375 ~ 385 kpa (3.82 ~ 3.92 kgf/

, 54.3 ~ 55.8 psi)

 

If the measured fuel pressure differs from the standard value, perform the necessary repairs 
using the table below.

5.  Stop the engine and check for a change in the fuel pressure gauge reading.

After engine stops, the gage reading should hold for about 5 minutes

 

Observing the declination of the fuel pressure when the gage reading drops and perform the 
necessary repairs using the table below.

5. FUEL PRESURE TEST

Fuel Pump

Condition

Supected Area 

Injector

Injector leak

The check valve within the 
fuel pump is open

Probable Cause

Fuel pressure drops 
slowly after engine is 
stopped

Fuel pressure drops 
immediately after engine 
is stopped

1.  Connect the battery negative (-) terminal.
2.  Apply battery voltage to the fuel pump terminal and activate the fuel pump. With fuel pressure applied, 

check that there is no fuel leakage from the fuel pressure gauge or connection part.

4. INSPECT FUEL LEAKAGE ON CONNECTION

FUEL SYSTEM

1.  Disconnect the Fuel Pressure Gage and Hose (09353-24100) from the Fuel Pressure Gage Connector 

(09353-24000).

2.  Disconnect the Fuel Pressure Gage Connector (09353-24000) from the Fuel Pressure Gage Adapter 

(09353-38000).

3.  Disconnect the fuel feed hose from the Fuel Pressure Gage Adapter (09353-38000).
4.  Disconnect the Fuel Pressure Gage Adapter (09353-38000) from the delivery pipe.

5.  Conenct the fuel feed hose to the delivery pipe.

7. REMOVE THE SPECIAL SERVICE TOOL (SST) AND CONNECT THE FUEL LINE

1.  Connect the battery negative (-) terminal.
2.  Apply battery voltage to the fuel pump terminal and activate the fuel pump. With fuel pressure applied, 

check that there is no fuel leakage from the fuel pressure gauge or connection part.

3.  If the vehicle is normal, connect the fuel pump connector.

8. INSPECT FUEL LEAKAGE ON CONNECTION

Cover the hose connection with a shop towel to prevent splashing of fuel caused by residual pressure in the fuel line.

CAUTION

1.  Disconnect the fuel pump connector (A).     
2.  Start the engine and wait until fuel in fuel line is exhausted.
3.  After the engine stalls, turn the ignition switch to OFF position 

and diconnect the negative (-) terminal from the battery.

6. RELEASE THE INTERNAL PRESSURE

Be sure to reduce the fuel pressure before disconnecting the fuel feed 
hose, otherwise fuel will spill out.
