CONNECT FUEL EVAPORATION TUBE SUB-ASSEMBLY NO.1
Match the axis of the connector with the axis of the pipe, and push into the connector until the connector makes a 'click' sound. In case that the connection is tight, apply a small amount of fresh engine oil to the tip of the pipe.
Note
Check that there is any damage or foreign objects in the connected part of the pipe.
After finishing the connection, check if the pipe and the connector are securely connected by pulling them.

BLEED FUEL LINE
Check that the battery voltage is above 12 V.
Disconnect the negative terminal cable from the battery.
Disconnect the fuel hose from the fuel filter assembly.
Install SST (pressure gauge) using SSTs and a fuel tube connector as shown in the illustration.
Wipe off any splattered gasoline.
Reconnect the negative terminal cable to the battery.
Connect the intelligent tester to the DLC3 (See step 1 in check fuel pump operation).
Measure the fuel pressure.
| Fuel pressure |
|---|
| 281 to 287 kPa (2.87 to 2.93 kgf/cm2, 40.8 to 41.7 psi) |
If pressure is high, replace the fuel pressure regulator.
If pressure is low, check the fuel hoses, fuel hose connection, fuel pump, fuel filter and fuel pressure regulator.
Disconnect the intelligent tester from the DLC3.
Stop the engine.
Measure the fuel pressure at idle.
| Fuel pressure |
|---|
| 281 to 287 kPa (2.87 to 2.93 kgf/cm2, 40.8 to 41.7 psi) |
If pressure is not as specified, check the vacuum sensing hose and fuel pressure regulator.
Stop the engine.
Check that the fuel pressure remains as specified for 5 minutes after the engine has stopped.
| Fuel pressure |
|---|
| 147 kPa (1.5 kgf/cm2, 21 psi) or higher |
If pressure is not as specified, check the fuel pump, pressure regulator and/or injector.
After checking fuel pressure, disconnect the negative terminal cable from the battery and carefully remove the SST to prevent gasoline from splashing.
Connect the fuel hose to the fuel filter assembly.
Reconnect the negative terminal cable to the battery.
Check for fuel leakage.
CHECK FOR FUEL LEAKS
When using the intelligent tester
Connect the intelligent tester to the DLC3.
Turn the ignition switch to the on position and intelligent tester main switch ON.
Note
Do not start the engine.
Select the Active Test mode on the intelligent tester.
Tech Tips
Please refer to the intelligent tester operator's manual for further details.
When not using the intelligent tester.
Disconnect the fuel pump connector.
Using a service wire, connect terminals FP and +B of the relay block.
Note
Pay attention to the terminal connecting position to avoid a malfunction.
Turn the ignition switch to the ON position, and check that the fuel pump operates.
Note
Do not start the engine.
Check that there are no fuel leaks anywhere on the fuel system after doing maintenance.
Check that the pulsation damper screw rises up when the fuel pump operates.
If operation is not as specified, check the following parts:
Fusible link
Fuel pump
Wiring connections
ECM
Fuses
Turn the ignition switch off.
Disconnect the intelligent tester from the DLC3.
