Warning: The following procedure simply relieves the pressure in the fuel system. Remember that fuel is still in the system components, so take precautions before disconnecting them. Follow the Chapter 2.
General description
1. The fuel system consists of a fuel pump installed in the tank, a fuel filter, a fuel injector, and a pressure regulator in the throttle body. These components are connected by metal pipes and flexible hoses. All of them contain fuel that is under pressure when the engine is running and/or the ignition is on.
2. The pressure in the system remains for some time even after the ignition is turned off and must be released before disconnecting any component.
3. Remove the fuel lift pump fuse (number 11) or fuel lift pump relay, and start the engine. Let the engine idle until it stalls. Then crank the starter 1-2 times to make sure all pressure is released, then turn off the ignition.
4. Don't forget to put the fuse or relay back.
