6.3.2. Models with multipoint electronic injection of fuel

The power supply system consists of the fuel tank installed under the bottom in a back part of the car, the electric fuel pump installed in the fuel tank, the fuel filter, the pipeline of supply of fuel and the return pipeline. The fuel pump gives fuel to a fuel collector which serves as the tank for four fuel injectors which inject fuel into inlet channels. The fuel filter is installed in the pipeline going from the fuel pump to a fuel collector and serves for purification of the fuel arriving on injectors.

The Phase I models (release till June, 1993) and "Phase II" are mentioned in this section (release after June, 1993). On cars with the 1.6 liters engine the multipoint system of injection of fuel (a GA16DE engine code) was established, only, since the models "Phase II" (release after June, 1993). On cars with the 2.0 liters engine, can determine car model ("Phase I" or "Phase II") by a form of an inlet collector. On the models "Phase I" the case of a butterfly valve is installed on the basis of an inlet collector, and the collector rises to a head of the block of cylinders up; fuel injectors are located from above an inlet collector and are easily available. On the models "Phase II" the case of a butterfly valve is installed from above an inlet collector, and the collector falls down to a head of the block of cylinders; fuel injectors are less available.


Prevention

When carrying out many operations it is necessary to remove or disconnect fuel tubes that can lead to fuel leak. Gasoline is very dangerous and flying liquid and during the work with it extra care is required.

Residual pressure remains in fuel tubes for a long time after the car was in the movement. Before a detachment of any fuel tubes, release pressure from fuel system, being guided by the instructions provided in subsection 6.3.2.6.
