Ignition

Your ignition system is responsible for starting and maintaining the operation of the engine. Ignition failure is not only frustrating but potentially dangerous. Here is a brief overview of automotive ignition and potential signs of ignition failure.

The components of an ignition system:

Battery

Ignition switch

Starter

Key fob

Spark plugs

Ignition coil

Distributor

Engine control module (ECM)

When the key is turned in the ignition switch, power is sent from the battery to the starter. The starter motor then turns the engine over, and the ECM sends a signal to the ignition coil to produce a spark, which ignites the fuel and air mixture in the engine. This process starts the engine and maintains its operation.

Signs of ignition failure:

Engine cranks but does not start

Engine stalls while driving

Engine misfires or runs rough

Delayed start or slow cranking

Check engine light or other warning lights show up on the dashboard

Causes of ignition failure:

Dead battery or damaged battery terminals

Faulty ignition switch

Defective starter

Malfunctioning key fob or immobilizer system

Failed spark plugs or ignition coil

Damaged distributor

Faulty ECM or other related components

Preventive measures:

Keep the battery and terminals clean and free of corrosion

Replace spark plugs and ignition coil at recommended intervals

Regularly check the ignition switch and starter for signs of wear and tear

Repair or replace warning lights immediately upon detection
