GENERAL INFORMATION

The engine is not started or becomes deaf at once after start:

  – the relay of system of injection is faulty;
  – the fuel pump is faulty;
  – the fuel system is untight;
  – fuel nozzles are faulty;
  – pressure sensor is faulty;
  – the speed sensor is faulty;
  – the output block of ignition is faulty;
  – the sensor of temperature of cooling liquid is faulty;
  – the control unit is faulty;
  – damage of an electrical wiring.

Unstable operation of the engine on idling turns:

  – the butterfly valve is not closed;
  – low pressure in the fuel highway;
  – the fuel nozzle is faulty;
  – an air suction in system of injection.

Weak acceleration:

  – the faulty or incorrectly adjusted potentiometer switch;
  – additional suction of air;
  – the control unit is faulty;
  – the electrical wiring is damaged.

The increased fuel consumption:

  – nozzles are faulty;
  – high pressure in the fuel highway;
  – the sensor of temperature of cooling liquid is faulty;
  – the control unit is faulty;
  – the electrical wiring is faulty.
