What can I check if my 1988 Mazda 323 has no spark commimg from the coil?

- Check the ignition coil:

- Make sure that the ignition coil is properly connected to the distributor and that the wiring is intact.

- Disconnect the ignition coil from the distributor and check between the connector and cylinder 1 tower of the ignition coil. If you have voltage coming from the coil that is not ignition voltage that could be over 35kV.

- Disconnect the wire from the coil to the distributor cap and check the resistance reading of the coil. The ideal resistance value varies depending on the specific model and year of your Mazda 323, so refer to your vehicle's service manual for the correct value. If the resistance reading is too high or too low, the coil may be faulty and need to be replaced.

- Connect the ignition coil to a spark tester and crank the engine. If there is no spark, the coil may be defective and need to be replaced.

- Check the distributor cap and rotor:

- Remove the distributor cap and inspect the inside for any signs of damage, corrosion, or cracks.

- Check the rotor for any damage or wear.

- If the distributor cap or rotor is damaged, replace them.

- Check the spark plug wires:

- Check the spark plug wires for any signs of damage, corrosion, or cracks.

- Make sure the wires are properly connected to the spark plugs and the distributor cap.

- If the spark plug wires are damaged, replace them.

- Check the ignition module:

- The ignition module is responsible for sending the electrical signal to the ignition coil. If the ignition module is faulty, it can cause the coil to not receive any spark. Check the ignition module according to the manufacturer's instructions and replace it if necessary.

- Check the battery and starter

- Ensure the battery has enough power to start the engine and that the starter motor is functioning properly. A weak battery or faulty starter can cause insufficient electrical current to reach the ignition coil, affecting the spark generation process.
