In connection with a high voltage developed by system of ignition, it is necessary to accept safety measures at carrying out of any works on components of system of ignition.
The general check of system of ignition carry out as follows:
If the engine is turned by a starter, but not started, disconnect a high-voltage wire from any spark plug and connect it to the additional serviceable candle which case is reliably fixed on the engine.
Dump pressure in fuel system. At check of system of ignition do not connect an electric socket of the fuel pump.
Turn a cranked shaft and attentively look at an interelectrode backlash of an additional candle. In it should slip bright dark blue sparks periodically.
At presence искрообразования serially remove and connect high-voltage wires to a control spark plug. Presence искрообразования on each high-voltage wire testifies to serviceability of coils of ignition. However spark plugs can be polluted, therefore turn out and clear or replace them with the new.
If искрообразование is absent or very unstable, check up chains of giving of pressure to coils of ignition and resistance of windings of coils of ignition, and also a condition and resistance of each high-voltage wire.
If all checked up components and electric chains
are serviceable on models with 1996 on 1997, probably, the ignition coil, and on models since 1998, probably is faulty, are faulty the gauge of position of a camshaft and / or the gauge of an angle of rotation of a cranked shaft.
