| 1. Disconnect a wire from the negative plug of the storage battery. |
| 2. Remove pressure in fuel system. |
| 3. Lift the car. |
| 4. Connect measuring device OK2A1 131 001 And about the fuel filter. |
| 5. Connect a wire to the negative plug of the storage battery. |
|
6. An additional wire connect plugs FUEL PUMP (the fuel pump) and In + a 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 up pressure in fuel system.
Pressure in fuel system: 320–350 кПа
|
If pressure exceeds demanded values:
– Check up cleanliness of the pipeline of return of fuel;
– If the pipeline of return of fuel is not polluted, replace a pressure regulator.
If pressure below demanded value:
– Close the pipeline of return of fuel and check up, 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 the plugs of a diagnostic socket. |
