Fuel Pressure Relief

CAUTION: Do not perform this procedure when engine is hot. Doing so may have an adverse effect on catalytic converter.
  1. Place transmission in neutral (M/T) or park (A/T). Set parking brake and block drive wheels. Disconnect fuel pump relay. See FUEL PUMP RELAY LOCATION  table.
  2. Remove fuel filler cap to release fuel vapor pressure in fuel tank. Reinstall fuel filler cap. Start engine and run until engine dies. After engine dies, crank engine 2-3 times for about 3 seconds to dissipate fuel pressure in lines. When repairs are complete, to restore normal operation, reinstall fuel pump relay.
