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

  • If any ignition parts start to fail, replace them as soon as possible to maintain consistent performance.
