5.1.9. Pressure removal in fuel system



At work on fuel system it is necessary to remove previously pressure in system.

SOCH engines of 1,6 l

1. Switch off ignition.
2. Uncover the relay block.
3. Take the relay of the fuel pump (the relay of violet color).
4. Start the engine in an idling mode to an engine stop.
5. Remove a weight wire from the accumulator and establish the relay in the block of the relay and close a cover of the block of the relay.

L DOCH 1.6, 1.8 and 2 engines

On these engines pressure in fuel system can be removed by a method described above, or as follows.
1. Unscrew a stopper from the valve of removal of pressure and establish the corresponding container under the valve.
2. On engines of 1,6 l the valve is located at an end face of the fuel highway (it is specified by an arrow).
3. On l engines 1,8 and 2,0 the valve is located from above the fuel highway (it is specified by an arrow).
4. A screw-driver press a valve zolotnik, thus it will leave fuel, and remove pressure in fuel system.
5. Screw a stopper on a head of the valve of removal of pressure.
