Fuel System Pressure Release
Loosen the fuel filler cap in order to relieve the fuel tank pressure. Remove the circuit opening relay located at the lower left side of the driver's compartment, above the kick panel. Crank the engine and allow the engine to stall. Crank the engine for an additional 3 seconds in order to ensure relief of any remaining fuel pressure. Disconnect the negative battery cable in order to avoid re-pressurizing the fuel system. Install the circuit opening relay. Tighten the fuel filler cap.
