DISCHARGE FUEL SYSTEM PRESSURE
Check that the battery positive voltage is above 12 V.
Discharge the fuel system pressure Click here.
Disconnect the negative terminal cable from the battery.
Pinch and pull the No. 1 fuel hose (fuel tube connector) to disconnect it from the fuel pressure pulsation damper assembly.
CAUTION:
Always read the precautions Click here before disconnecting the fuel tube connector (quick type).
The fuel tube may spray fuel as a result of pressure that remains in it. Do not allow fuel to be sprayed in the engine compartment.

| *2 | No. 1 Fuel Hose |
| *a | SST (Fuel Tube Connector) |
| *b | SST (Hose Band) |
| *c | SST (Hose) |
| *d | SST (T-Joint) |
| *e | SST (Hose Joint) |
| *f | SST (Pressure Gauge) |
Install SST (pressure gauge) as shown in the illustration.
Wipe off any gasoline.
Reconnect the negative terminal cable.
Operate the fuel pump.
Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON.
Note
Do not start the engine.
Turn the intelligent tester on.
Enter the following menus: Powertrain / Engine and ECT / Active Test / Control the Fuel Pump / Speed.
Measure the fuel pressure.
| Standard fuel pressure |
|---|
| 281 to 287 kPa (2.87 to 2.93 kgf/cm2, 40.8 to 41.7 psi) |
If the pressure is higher than the specification, replace the fuel pressure regulator assembly.
If the pressure is lower than the specification, check the fuel hoses and connections, fuel pump, fuel filter assembly and fuel pressure regulator assembly.
Start the engine.
Measure the fuel pressure.
| Standard fuel pressure |
|---|
| 281 to 287 kPa (2.87 to 2.93 kgf/cm2, 40.8 to 41.7 psi) |
If the pressure is not as specified, check the fuel pump, fuel pressure regulator assembly and/or fuel injector assemblies.
Stop the engine.
Check that the fuel pressure remains as specified for 5 minutes after the engine has stopped.
| Standard fuel pressure |
|---|
| 147 kPa (1.5 kgf/cm2, 21 psi) or more |
If the pressure is not as specified, check the fuel pump, fuel pressure regulator assembly and/or fuel injector assemblies.
After checking the fuel pressure, disconnect the negative terminal cable and carefully remove SST and the fuel tube connector to prevent gasoline from spraying.
Reconnect the No. 1 fuel hose (fuel tube connector) to the fuel pressure pulsation damper assembly.

| *2 | Fuel Tube |
| *3 | O-Ring |
| *4 | Tube Joint Clip |
Remove the tube joint clip and pull the fuel tank return tube out of the plug of the fuel suction with pump and gauge tube assembly.
Note
Remove any dirt and foreign matter on the fuel tube joint before performing this step.
Do not allow any scratches or foreign matter on the parts when disconnecting them as the fuel tube joint contains the O-rings that seal the plug.
Perform this step by hand. Do not use any tools.
Do not forcibly bend or twist the nylon tube.
Protect the disconnected parts by covering them with plastic bags and tape after disconnecting the fuel tubes.
