2. To do this, disconnect the wire from one of the spark plugs, remove the insulating tip and secure the wire at a distance of about 6 mm from the exposed mass, or connect it to a calibrated spark gap. Turn on the starter and watch the spark plug wire. An intense blue spark should appear.
3. If there is a spark, remove the spark plugs and check.
4. If there is no spark or spark formation is unstable, remove the distributor cap and check the condition of the cap and rotor.
5. If moisture is detected, wipe the cover and slider dry, replace the cover and repeat the check.
6. If there are still no sparks, disconnect the high-voltage wire of the ignition coil from the distributor cap and secure the wire at a distance of about 6 mm from the exposed ground area.
7. If a spark appears, the cause may be a faulty distributor cap or rotor.
8. If there is no spark, check all primary circuit wiring to the ignition coil.
9. Check if voltage is supplied to the coil from the ignition key.
10. Check the ignition coil (see subsection 11.4) and an inductive sensor.

11. If there is still no spark, replace the coil high-voltage wire with a known good one.
12. If replacement does not produce results, then the electronic unit is faulty.
