Why my Vauxhall Movano is not starting?

My Vauxhall Movano is not starting up properly. I have changed the battery and the fuel filter, but it still won't start. What could be the problem?

The issue could be with your starter motor or the ignition system. You may need to take your van to a mechanic to get it checked.

Have you checked your spark plugs? They might need to be replaced if they are worn out. Also, make sure your fuel pump is in good condition.

Another possible cause could be a faulty electrical connection. Check all the connections to the battery and the engine to ensure they are secure.
