2. If all these parts are in good condition, then check the integrity of the high-voltage wires. To do this, turn off the ignition, disconnect the coil wire from the distributor and fasten it 45 mm from the stripped area of \u200b\u200bthe mass. Crank the engine over with the starter and watch for sparks. If there are sparks, you should look for a malfunction in other engine systems. If there is no spark, or sparks are observed intermittently, then a further check of the ignition system is necessary.
3. Warm up the engine (if you can run) and stop.
4. Check up pressure on the battery at the switched off ignition and consumers. If the voltage is below 11.5V, then remove the battery and charge (if the battery has not been left under load for a long time, then check the charge circuit).
5. If the voltage on the battery when the starter is turned on is below 9.6 V, then the battery is not fully charged. Remove the battery and charge.
6. Check the distributor cap and wires. If, when measuring the resistance of the spark plug wire connected to the distributor cap, the ohmmeter reading is less than 30 Kom (photo), then the output of the cover and the wire are OK.
7. On cars 1987-1988 check the insulation resistance between the cover electrodes (photo). If the resistance is below normal, replace the cover.

8. Check the resistance of the secondary winding of the ignition coil by connecting an ohmmeter with the ignition off between the high-voltage terminal and terminal H of the coil (photo). If the ohmmeter reading is not correct, replace the coil.
