FUEL SYSTEM - PRECAUTION

CAUTION:

Before working on the fuel system, disconnect the cable from the negative (-) battery terminal.

Do not smoke or be near an open flame when working on the fuel system.

Keep gasoline away from rubber and leather parts.

1.DISCHARGE FUEL SYSTEM PRESSURE

CAUTION:

Do not disconnect any part of the fuel system until you have discharged the fuel system pressure.

After discharging the fuel pressure, place a cloth or equivalent over fittings as you separate them to reduce the risk of fuel spray on yourself or in the engine compartment.

Disconnect the fuel pump ECU connector ().

Start the engine. After the engine stops, turn the engine switch off.

HINT:

DTC P0171/0174 (system too lean) may be stored.

Crank the engine again, and then check that the engine does not start.

Loosen the fuel tank cap, and then discharge the pressure in the fuel tank completely.

Disconnect the cable from the negative (-) battery terminal.

NOTICE:

After turning the engine switch off, waiting time may be required before disconnecting the cable from the battery terminal. Therefore, make sure to read the disconnecting the cable from the battery terminal notice before proceeding with work ().

When disconnecting the cable, some systems need to be initialized after the cable is reconnected ().

Connect the fuel pump ECU connector ().

2.FUEL SYSTEM

When disconnecting the high fuel pressure line, a large amount of gasoline will spill out. Follow these procedures.

Perform the "DISCHARGE FUEL SYSTEM PRESSURE" procedures above.

Disconnect the fuel tube.

Drain any fuel remaining inside the fuel tube.

To protect the disconnected fuel tube from damage and contamination, cover it with a plastic bag.

Put a container under the connecting part of the pressure line.
