Due to the high voltage developed by system of ignition it is necessary to take precautionary measures when carrying out any works on components of system of ignition.
Carry out the general check of system of ignition 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 an additional serviceable candle which case is reliably fixed on the engine.
Dump pressure in fuel system. When checking system of ignition do not connect the electric socket of the fuel pump.
Turn a bent shaft and attentively you look at an interelectrode gap of an additional candle. In it have to slip bright blue sparks periodically.
In the presence of sparking serially remove and connect high-voltage wires to a control spark plug. Existence of sparking 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 new.
If sparking 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 state and resistance of each high-voltage wire.
If all checked components and
are serviceable on models from 1996 to 1997, perhaps, the ignition coil, and on models since 1998, perhaps is faulty, the sensor of position of the camshaft and / or the sensor of an angle of rotation of a bent shaft are faulty.
