5.3. Checks of system of injection of MFI

If MFI system components (sensors, ESM, nozzles etc.) fail, supply of fuel in engine cylinders on various operational modes that leads to the following situations is broken:

the engine is started hardly or not started: the engine idling works unstably; the engine works at all modes unstably.

In the presence of any of aforementioned situations, first of all execute usual diagnostics (system of ignition, engine adjustment etc.) then check MFI system components.
