Vehicle Damage Warnings
PRECAUTION1. BEFORE WORKING ON FUEL SYSTEM, DISCONNECT NEGATIVE (-) TERMINAL CABLE FROM BATTERY
2. DO NOT SMOKE OR WORK NEAR AN OPEN FLAME WHEN WORKING ON FUEL SYSTEM
3. KEEP GASOLINE AWAY FROM RUBBER AND LEATHER PARTS
4. DISCHARGE FUEL SYSTEM PRESSURE
NOTE:
- Perform the following procedures to prevent fuel from spilling out before removing any fuel system parts.
- Pressure will still remain in the fuel line even after performing the following procedures. When disconnecting the fuel line, cover the opening with a shop rag or a piece of cloth to prevent fuel from spraying.
a. Using the F/PMP relay:
1. Remove the engine room R/B cover upper.
2. Remove the F/PMP relay.
3. Start the engine.
4. After the engine has stopped, turn the ignition switch OFF.
NOTE: DTC P0171 and P0174 (Lean fuel-trim) may be present. Clear DTCs after the repair.
5. Crank the engine. Check that the engine does not start.
6. Remove the fuel tank cap to discharge pressure from the fuel tank.
7. Disconnect the negative (-) battery terminal cable.
8. Reinstall the F/PMP relay.
b. Using the fuel pump connector:
1. Remove the rear seat cushion.
2. Remove the rear floor service hole cover.
3. Disconnect the fuel pump connector.
4. Start the engine.
5. After the engine has stopped, turn the ignition switch OFF.
NOTE: DTC P0171 and P0174 (Lean fuel-trim) may be present. Clear DTCs after the repair.
6. Crank the engine. Check that the engine does not start.
7. Remove the fuel tank cap to discharge pressure from the fuel tank.
8. Disconnect the cable from the negative (-) battery terminal.
9. Reconnect the fuel pump connector.
10. Install the rear floor service hole cover.
11. Install the rear seat.
5. FUEL SYSTEM
a. When disconnecting the high fuel pressure line, a large amount of gasoline will spill out. Observe these procedures:
1. Perform the "DISCHARGE FUEL SYSTEM PRESSURE" procedures above. Put a container under the connection.
2. Disconnect the fuel tube.
3. Drain the fuel remaining inside the fuel tube.
4. Protect the disconnected fuel tube from damage and foreign material by covering it with a plastic bag.
b. When connecting the union bolt (fuel pressure pulsation damper) on the high pressure pipe union, observe these procedures:
1. Always use 2 new gaskets.
2. Tighten the union bolt by hand.
3. Using SST, tighten the union bolt to the specified torque.
SST 09612 24014 (09617 24011)
Torque: 33 N.m (340 kgf.cm, 24 ft.lbf) for use with SST 39 N.m (400 kgf.cm, 29 ft.lbf)
HINT: Use a torque wrench with a fulcrum length of 30 cm (11.81 in.).
c. Observe these precautions when removing and installing the injector.
1. Never reuse the O-ring.
2. When placing a new O-ring on the injector, take care not to damage it.
3. Coat a new O-ring with spindle oil or gasoline before installing. Never use engine, gear or brake oil.
d. Install the injector to the delivery pipe and the lower intake manifold as shown in the illustration. Before installing the injector, apply spindle oil or gasoline on the place where the delivery pipe or intake manifold touches O-ring of the injector.
e. Observe these precautions when disconnecting the fuel tube connector (quick type):
1. Disengage the lock claw by lifting up the cover, as shown in the illustration.
2. If the connector and pipe are stuck, pinch the connector, and push and pull the pipe to disconnect them. Do not use any tools.
3. Check for foreign matter on the seal surface of the disconnected pipe. Clean it if necessary.
4. To protect the disconnected pipe and connector from damage and foreign matter, cover it with a plastic bag.
f. Observe these precautions when connecting the fuel tube connector (quick type).
1. Check that there is no damage or foreign matter on the part of the pipe that contacts the connector.
2. Align the axis of the connector with the axis of the pipe. Push the pipe into the connector until the connector makes a "click" sound. If the connection is too tight, apply a small amount of fresh engine oil on the tip of the pipe.
3. After connecting the pipe and connector, try to pull them apart to confirm that they are securely connected.
4. Install the No. 1 fuel pipe clamp to the connector.
6. CHECK FUEL LEAK
a. Check that there are no fuel leaks after doing maintenance anywhere on the fuel system.
1. Connect the hand held tester (with CAN VIM) to the DLC3.
2. Turn the ignition switch ON and hand held tester main switch ON.
NOTE: Do not start the engine.
3. Select the ACTIVE TEST mode on the hand held tester.
HINT: Please refer to the hand held tester operator's manual for further details.
4. Check that there are no leaks from any part of the fuel system.
5. Turn the ignition switch LOCK.
6. Disconnect the hand held tester from the DLC3.
