What should I do if my Vauxhall Corsa's engine won't start?

I recently tried to start my Vauxhall Corsa, but the engine won't start. I checked the battery and it seems to be fine. What could be causing this issue and what steps should I take to fix it?

First, double check that all connections to the battery are secure. If that doesn't resolve the issue, it's possible that there is an issue with the starter or ignition system.

Another common cause for an engine not starting could be a faulty fuel pump. If you can hear a humming noise from the back of your car when you turn the ignition, the fuel pump may need to be replaced. It's best to take your car to a mechanic for a proper diagnosis.

If you have been experiencing any issues with your key or key fob, it's possible that they could be causing the engine not to start. Try using a spare key or getting a new key programmed by a dealership.
