How to troubleshoot engine starting issues in a Vauxhall Movano?

I have been experiencing some difficulties in starting my Vauxhall Movano's engine lately. It takes a couple of tries and sometimes makes a strange noise before finally starting up. What could be the problem and what steps can I take to fix it?

First thing to check would be the battery. Make sure it is fully charged and there isn't any corrosion on the terminals.

It could also be an issue with the fuel system. Check the fuel pump and filters for any clogs or malfunctions.

You may also want to check the spark plugs. If they are old or worn out, they could be causing the engine starting issues.

If none of the above solutions work, it could be a problem with the ignition system. Get it checked by a professional mechanic.
