Warning! Remember that gasoline is a highly flammable liquid! Observe all applicable fire safety precautions when working on power system components. Do not smoke! Do not approach the place of work with an open flame or carrying an unprotected lampshade! Do not service the system in rooms equipped with natural gas-fired heaters equipped with a pilot flame (such as water heaters and clothes dryers). Do not forget that gasoline is one of the carcinogenic substances, i. substances that promote the development of cancer! Try to avoid getting fuel on open areas of the body, use rubber protective gloves, in case of accidental unexpected contact with fuel, thoroughly wash your hands with warm water and soap. Clean up spilled fuel immediately and do not store fuel-soaked rags near open flames. Remember that the fuel injection system of models equipped with fuel injection is constantly under pressure. Relieve any residual pressure in the system before attempting to disconnect the fuel lines. Wear safety goggles when servicing power system components. Keep a class B fire extinguisher handy at all times!
1. Depressurize the fuel system before servicing any of its components to minimize the risk of fuel ignition and personal injury.
2. To relieve excess pressure in the fuel tank, remove the filler cap.
3. There are two ways to relieve pressure in the power system: disconnect the fuel pump electrical wiring connector, or remove the Circuit Opening Relay, evaluate which of the actions can be performed with less effort and time. The pump wiring connector is located directly on the fuel tank assembly (see Section Removal and installation of the fuel pump).
4. Start the engine and wait for it to stop spontaneously, then turn the ignition key to the OFF position.
5. To ensure that the system is completely discharged, turn the engine a few more times with the starter. Disconnect the negative cable from the battery.
Attention! If the stereo system installed in the car is equipped with a security code, before disconnecting the battery, make sure that you have the correct combination to activate the audio system!
6. When disconnecting the fittings, wrap them with paper towels to collect spilled fuel.
