Ignition problems refer to issues that prevent a vehicle's engine from starting. Common causes include a dead battery, faulty ignition switch, or issues with the starter motor. These problems can lead to frustrating situations, especially when you need to use your vehicle. To diagnose ignition problems, it's essential to check the battery's charge and connections first. If the battery is fine, the next step is to inspect the ignition system, which includes components like spark plugs and ignition coils. Identifying the root cause can help in determining the necessary repairs to get the vehicle running again.
