Ignition system — check (Mazda Capella GE)

The ignition system provides complete control over the ignition timing adjustment. The electronic control unit determines the optimal ignition timing for a given speed, engine temperature, throttle position and intake manifold vacuum.

Ignition system with distributor

The distributor ignition system is installed on all models except 1998 models. The system consists of an ignition switch, battery, ignition coil and distributor, electronic control unit, high-voltage wires and spark plugs.

Ignition system without distributor (1998 models only)

This system consists of an ignition coil with a separate terminal for each cylinder, as well as the corresponding sensors and an electronic control unit.

Examination

Ignition system with distributor

1. First of all, check the connecting wires and the reliability of the connections. Check the battery charge and the fuse jumpers in the engine compartment.



2. Check for spark at the spark plugs.

3. If there is no spark, check the distributor cap, rotor and high tension wires.



4. Check for voltage on the high voltage wire coming from the secondary winding of the ignition coil.



5. Check for voltage on the primary winding of the ignition coil. Check the resistance of the ignition coil windings.

6. Replace faulty elements.

7. Check for spark at each spark plug in turn.

8. Check the resistance of the ignition coil windings. Check the voltage supply to the ignition coil.

9. Check the resistance of the high voltage wires. Replace faulty elements.
