GENERAL INFORMATION

In system of injection of fuel self-standing telno it is possible to check only the main electric chains.

If normal operation of the engine is broken, first of all check a condition of electric conducting and sockets. Check a condition of a filtering element of the air filter, and also a condition and an interelectrode gap of spark plugs. Check passableness of hoses of ventilation of a case of the engine and adjustment of a cable of an accelerator. If the engine still works unstably, check a compression in engine cylinders.

If there is a suspicion for bad work of a fuel nozzle, clean it.

If the engine still works unstably, check elements of system of ignition.

If malfunction is not eliminated yet, check integrity fusible предохра nitel and a condition of electric sockets and electroconducting. On electric sockets there should not be melted-off contacts, moisture, traces of corrosion, dirt and other damages.

After carrying out independent check address on specialized station Opel for diagnostics of system of injection of fuel on the special equipment.
