Note. Measurement of the pressure on the line between the high pressure fuel pump and the injectors must be carried out after you make sure that the pressure of the fuel generated by the pump (between low and high pressure side) fine.
1. Connect the MUT-II to the diagnostic socket.
2. Disconnect the intermediate connector of the injectors (pic. 6.15, 6.16).

3. Turn the key in the ignition switch to the ON position.
4. Select item #74 from the Data list menu (data table) instrument MUT-II.
5. Crank the engine with the starter for 2 seconds and visually check that there are no fuel leaks from the connections.
Warning. If there are fuel leaks, stop the engine immediately and fix the source of the leak.
6. Make sure that the fuel pressure is maintained at least 1 MPa for 20 seconds after the starter has finished cranking the engine.
7. If the fuel pressure is below 1 MPa, it means that there are leaks in the high pressure line and it is necessary to check the fuel system.
8. Turn the key in the ignition switch to the OFF position.
9. Connect an intermediate socket of atomizers.
10. Start the engine and let it idle.
11. While the engine is idling, measure the fuel pressure.
Rated pressure: 4.0-7.0 MPa
12. Make sure that the fuel pressure at idle does not drop even after several presses on the accelerator pedal.
13. If any fuel pressure is out of tolerance, diagnose and repair in accordance with the Fuel System Pressure Diagnosis Chart.
Fuel system pressure diagnostic table
14. Stop the engine and turn the key in the ignition switch to the OFF position.
15. Disconnect the MUT-II device from a diagnostic socket.
