Attention! Due to the high voltage generated by the ignition system, precautions must be taken when carrying out any work on the components of the ignition system.
Perform a general check of the ignition system as follows:
If the engine turns over with the starter but does not start, disconnect the high voltage wire from any spark plug and connect it to an additional good spark plug that is securely attached to the engine.
Relieve pressure in the fuel system. When checking the ignition system, do not connect the fuel pump electrical connector.
Turn the crankshaft and carefully look at the electrode gap of the additional candle. It should periodically skip bright blue sparks.
In the presence of sparking, alternately remove and connect the high-voltage wires to the control spark plug. The presence of sparking on each high-voltage wire indicates the serviceability of the ignition coils. However, the spark plugs themselves can be dirty, so turn them out and clean them or replace them with new ones.
If there is no or very intermittent sparking, check the voltage supply circuits to the ignition coils and the resistance of the ignition coil windings, as well as the condition and resistance of each high voltage wire.
If all tested components and circuits are OK on 1996 to 1997 models, the ignition coil may be faulty, and on 1998 models, the camshaft position sensor and/or crankshaft angle sensor may be faulty.
