Contents: Examination ⇓ Replacing the ignition coil ⇓
The ignition coil should be checked when there is no spark from the spark plugs when the engine is cranked by the starter.
The ignition coil is checked using an ohmmeter.
Turn off the ignition.
1.25/1.4L Engine: Remove six bolts and engine cover.
Note: On the 1.3L engine, the ignition coil is located on the rear side of the cylinder block.
Examination
Disconnect all four high-voltage wires from the ignition coil by squeezing the two tabs on each plug.
Check the resistance of the primary winding: to do this, remove the plug by pressing the metal bracket.
The figure shows the plug (1) of the ignition coil. Connect the ohmmeter to the corresponding contacts of the ignition coil and measure the resistance between the following contacts in turn:
- between contacts 1 and 2;
- between contacts 3 and 2.
The resistance value for both measurements (resistance of primary windings of ignition coils) equals 0.4 - 0.6 Ohm.
If the value differs significantly from the specified values, replace the ignition coil.
Note: The resistance of the secondary winding (between the spark plug contact and ground) is not measured.
Replacing the ignition coil
Unscrew the mounting bolts and remove the ignition coil.
Install a new ignition coil, tighten the bolts to 6 Nm, insert the side plug.

Place the high-voltage wires on the ignition coil, making sure that the fastening tabs snap into place.
Note: The high-voltage wire bushings on the ignition coil are marked with numbers from 1 to 4. The wires must be installed in the correct order: 1-3-4-2 (1.3L engine: 1-2-4-3). The first cylinder is located next to the poly V-belt.
1.25/1.4L Engine: Install the engine cover and secure it with six bolts.
