1. Disconnect a wire from the negative plug of the storage battery. |
2. Remove pressure in fuel system. |
3. Lift the car. |
4. Connect the measuring device ОК2А1 131 001 A about the fuel filter. |
5. Connect a wire to the negative plug of the storage battery. |
|
6. An additional wire connect FUEL PUMP plugs (the fuel pump) and In + the diagnostic socket. |
7. Include ignition no more than on 10 with therefore the fuel pump will start to work and will create demanded pressure in fuel system. |
|
8. Check pressure in fuel system.
Pressure in fuel system: 320–350 kPas
|
If pressure exceeds demanded values:
– check purity of the pipeline of return of fuel; – if the pipeline of return of fuel is not polluted, replace a pressure regulator.
If pressure is lower than demanded value:
– close the pipeline of return of fuel and check, whether pressure raises; – if pressure raises, replace a pressure regulator; – if pressure does not raise, measure the maximum pressure created by the fuel pump. |
9. Switch off ignition and remove additional a wire connecting plugs of the diagnostic socket. |
