Ignition System Failure Warning Signs

Posted January 2, 2022

In order to ignite fuel and turn the motor over, gas-powered vehicles are reliant upon an effective ignition system. If the ignition process doesn’t go smoothly or isn’t functioning properly, your vehicle won’t be able to operate correctly and may fail its next emission test.

The vast majority of modern ignition systems are comprised of spark plugs/cables, a distributer and supporting components.

More often than not, your spark plugs will need to be the first component in your ignition system that will need to be replaced. As they get older, spark plugs tend to collect deposits that impede their ability to process electrical currents fluidly which can result in improper engine ignition.

If your engine isn’t igniting properly, it won’t burn all of its gas and the unburned fuel is expelled out into the atmosphere which hurts the environment and causes your vehicle to accelerate poorly. You should always have your spark plugs changed out or adjusted by a professional mechanic to ensure they’re properly set up to maximize their efficiency.

If spark plug cables begin to show signs of wear, they too should be replaced. These cables’ insulation begins to abate as they rub against various engine parts. Once their insulation wears out to a certain point, the electric current needed for ignition isn’t processed correctly which leads to engine problems.

Distributors are more durable than other ignition system components, and if they need servicing it’s not necessarily a precursor to failure. When distributor caps become cracked however, substances can infiltrate the system which can be harmful to the ignition process.
