How to fix a Vauxhall Astra that won't start?

My Vauxhall Astra seems to be having trouble starting, what could be the issue?

First, check the battery to make sure it has enough charge. If the battery is fine, then check the spark plugs and starter motor. These are common culprits for a car not starting. If those are fine, it might be a fuel issue. Try changing the fuel filter and see if that helps.

Another common issue with the Astra is the ignition switch. It may be faulty and causing the car not to start. Check the connections and if needed, replace the ignition switch.

If you have recently replaced the battery, make sure it is the correct size and type for your Astra. A wrong battery size or type can cause issues with starting.
