- Do not smoke or be near an open flame when working on the fuel system.
- Keep gasoline away from rubber and leather parts.
- 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.
- Remove the engine room side cover LH.
- Remove the engine room relay block cover.
- Remove the circuit opening relay (C/OPN).

- Crank the engine, then check that the engine does not start.
- Loosen the fuel tank cap, then discharge the pressure in the fuel tank completely.
