What is the reason for my Vauxhall Astra not starting?

I have a 2010 Vauxhall Astra and it has recently been struggling to start. It turns over but won't fully start up. I noticed this usually happens after it has been sitting overnight or for a few hours. Any ideas on what could be causing this issue?

It sounds like your fuel pump may be failing. This can cause difficulty starting the car after it has been sitting for a while. I would recommend getting it checked by a mechanic as soon as possible to prevent any further issues.

Another possibility could be a faulty ignition switch. This can cause intermittent starting issues and may need to be replaced. I suggest taking your car to a trusted mechanic for a proper diagnosis.

Have you checked your battery? If it is old or weak, it can cause trouble starting the car after it has been sitting for a while. Consider getting it tested or replaced.
