Note: Before you begin, read the safety precautions in Section General information and safety precautions.
Caution! There will be gasoline in the lines after performing the procedure below. Take all necessary precautions before disconnecting any fuel hose.
1. When the engine is running, the fuel inside the fuel system path is under pressure, which continues to be maintained for a considerable time after the ignition is turned off. Before disconnecting any of the system components, release the pressure in the stroke.
2. Nissan recommends using a diagnostic tool to relieve pressure "Consult-II", however, this operation can be carried out in another way.
3. De-energize the fuel pump circuit. To do this, remove its fuse (see Chapter On-board electrical equipment), or remove the rear seat assembly (see Chapter Body), open the service hatch cover and disconnect the fuel level sensor, fuel filter and fuel pump assembly connector (see section Removal and installation the fuel pump assembly, fuel filter and fuel level sensor).
4. Start the engine. After the engine stalls spontaneously, to ensure that the pressure is completely released, turn it over several times with the starter. If the engine fails to start, turn it over with the starter for several seconds. After completing the procedure, turn off the ignition and connect the connector/install the fuse.
5. Remember that after releasing pressure/removing fuel from the fuel system, it takes a little longer than usual to start the engine - you will have to turn the crankshaft with the starter until the pressure in the system is restored and the fuel fills all the fuel lines.
