What is Ignition Switch
It’s one of the most important electronic components found on many cars and trucks. It’s usually located on the steering column, just behind the ignition lock cylinder, which is where you put your key to crank your vehicle. The two work together to turn on and start the vehicle.
We realize that many vehicles are switching to keyless ignitions, but there are still many of vehicles that start by using a physical key. The ignition switch has several positions that power on different systems as the key is turned. Electrical accessories activate in the first position, power on the fuel and ignition systems on the second position, and the engine cranks on the third. As you can see, it controls almost all running aspects of your vehicle, so it’s critical for it to work properly. Since the ignition switch is used every time the vehicle is powered on and started, it will eventually wear out and begin to have issues.
A faulty ignition switch can produce any of the following 5 symptoms that can alert you of a potential issue. Before we take a look at them, remember that your auto repair experts at Hoover Automotive in Hoover, AL are ready to help with any car issues, including ignition switch failure.
Car stops while Driving
One of the first signs is a vehicle that suddenly stops while the engine is operating. We think you’d agree that this is probably the scariest sign too! If the ignition switch fails while the engine is still on, it may cut off power to the ignition and fuel systems, which will cause the engine to stall.
Depending on the exact issue, the vehicle may or may not be able to be restarted a short while later. If you’re close to Hoover Automotive when your vehicle starts acting up, please come by so we can take a look and see if your ignition switch is the problem.
Car Starts But Suddenly Stalls
A similar symptom is a car that starts and then suddenly stalls. If the ignition switch fails at the “on” position, the one meant to power on the fuel and ignition systems, it may result in the vehicle starting, then immediately stalling.
The ignition switch will momentarily provide power to the fuel pump and ignition system when it is in the cranking position, which may allow the vehicle to start. However, if it has failed in the “on” position, it will cut off power to the fuel and ignition systems as soon as the key is moved back to the “on” position. So essentially, you may be able to crank the car, but it may not stay that way once the key is in its resting position.
