10.3.4.1. Removal and installation

Install the gear shifting lever in neutral situation and slow down the car the parking brake.
As after an engine stop in a power supply system fuel pressure remains, first of all it is necessary to remove pressure. For this purpose disconnect a block of wires of a plait of system of injection from a block of wires of an electrogasoline pump. Start the engine and leave it to work to a stop. Include a starter for three seconds for removal of pressure in fuel-supply lines. Connect back electrogasoline pump wires to a plait of wires of system of injection.
Disconnect a wire from the minus plug of the rechargeable battery.
Remove the air filter and disconnect a cable of the drive of a butterfly valve from the unit of the central injection.
Disconnect fuel-supply lines from the unit of the central injection and close traffic jams the ends of tubes of fuel-supply lines for fuel dribble prevention.

Fig. 10-17. Unit of the central injection: 1 — the fuel pressure regulator; 2 — a nozzle; 3 — the fuel supply union; 4 — the sensor of provision of a butterfly valve; 5 — the union of removal of fuel in a tank; 6 — an adsorber purge branch pipe; 7 — a branch pipe of ventilation of a case of the engine; 8 — a branch pipe for connection of the sensor of absolute pressure; 9 — the idling regulator; 10 — the sector of the drive of a butterfly valve from a pedal in interior of the car

Disconnect electric wires from the sensor 4 (see fig. 10-17) provisions of a butterfly valve, a nozzle 2 and the regulator 9 of idling.
Remove from branch pipes of the unit of the central injection the vacuum hoses going to an adsorber and the sensor of absolute pressure and also a hose of system of ventilation of a case of the engine. At the same time pay attention to correctness of their connection at the subsequent assembly.
Turn off hairpins of fastening and remove from an inlet pipe the unit of the central injection with sealing laying. Close an entrance opening of an inlet pipe the cap excluding hit of any objects.
Carry out installation of the unit of the central injection upside-down. At the same time pay attention to a condition of sealing laying. After installation check fuel supply pressure as it is described further.

       NOTE
Are not subject to reuse the sealing laying which is established under the unit of the central injection, and sealing rings of fuel-supply lines
