2. Remove the fuel pump cover (A).
3. Disconnect the fuel pump connector (IN).
4. Start the engine and wait until the engine fuel hose is empty.
5. After the engine has stopped, turn the ignition key to the «OFF» and disconnect the wire from the negative battery terminal.
Note: Make sure the fuel system is depressurized before disconnecting the fuel line.
6. Disconnect the fuel line (1) from the fuel manifold (2).
7. Connect the pressure gauge adapter (3) between the fuel line and the fuel manifold. Connect fitting (4) to the pressure gauge adapter. Connect pressure gauge (3) to fitting (4), then connect the fuel line (1) to pressure gauge adapter (5).
8. Connect a wire to the negative plug of joint stock bank.
9. Apply battery voltage to the fuel pump connector to turn it on. With the pump running, check for fuel leaks through the gauge and connections.
10. Disconnect the wire to the negative terminal of the battery
11. Connect a socket of the fuel pump.
12. Connect a wire to the negative plug of joint stock bank.
13. Start the engine and measure the fuel pressure at idle. Rated value: 343 kPa. If the measured value is lower than the nominal value, this means that there are leaks in the fuel system, a dirty fuel filter, or a faulty pressure regulator. If the value is greater than the nominal value, check the operation of the pressure regulator.
14. Stop the engine and check the change in pressure. Within 5 minutes, the readings of the pressure gauge should not change. If pressure is applied quickly, check the fuel pump check valve for damage.
15. Disconnect the fuel pump connector.
16. Start the engine and wait until the fuel is completely pumped out.
17. After stopping the engine, turn off the ignition and disconnect the wire from the negative terminal of the battery.
18. Remove the pressure gauge with adapter and fitting. Connect the fuel pump connector.
19. Connect the wire to the negative battery terminal.
20. Connect the fuel line to the fuel manifold.
