What to do if my Vauxhall Vivaro is having trouble starting?

I've noticed that my Vauxhall Vivaro is having trouble starting, especially when it's been sitting for a while. What could be causing this and what should I do?

One common reason for this could be a weak battery. Try getting it checked and replaced if necessary.

It could also be an issue with your spark plugs. Have them checked and replaced if needed.

Another possibility is a faulty ignition switch. This can prevent the vehicle from starting. Get it checked and replaced by a mechanic.
