Due to the high voltage developed by system of ignition, it is necessary to accept precautionary measures at carrying out 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 the electric socket of the fuel pump.
Turn a cranked shaft and attentively look at an interelectrode gap of an additional candle. In it should slip bright dark blue sparks periodically.
In the presence of an iskroobrazovaniye serially remove and connect high-voltage wires to a control spark plug. Iskroobrazovaniye existence 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 the iskroobrazovaniye is absent or very unstable, check chains of giving of tension 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 components and
are serviceable on models from 1996 to 1997, possibly, the ignition coil, and on models since 1998, probably is faulty, the sensor of provision of a camshaft and / or the sensor of an angle of rotation of a cranked shaft are faulty.
