What should I do when my Vauxhall Zafira Life won't start?

My Vauxhall Zafira Life won't start when I turn the key in the ignition. I have checked the battery and it seems fine. What could be causing this issue and how can I fix it?

First, check the fuel level and make sure there is enough fuel in the tank. If the fuel level is low, try adding more fuel and see if that helps. If the problem persists, it could be an issue with the fuel pump or fuel filter.

Another possibility is a faulty starter motor. If the car makes a clicking sound when you turn the key, it could be a sign of a dead starter motor. In this case, you will need to replace the starter motor.

It could also be a malfunctioning ignition switch. If the car's lights and radio are working, but the engine won't start, it could be a sign of a faulty ignition switch. You can try cleaning the ignition switch or replacing it.

If none of these solutions work, it's best to bring your car to a certified mechanic for a professional diagnosis. They will be able to accurately identify the issue and provide a solution.
