Why is my Vauxhall Astra not starting?

My Vauxhall Astra is turning over but not starting. I've checked the battery and it seems fine. What could be the issue?

One possible reason could be a faulty ignition coil. You may need to get it checked and replaced.

Another possibility is a clogged fuel filter. You may want to get it cleaned or replaced.

It could also be an issue with the spark plugs. Try replacing them and see if that solves the problem.
