How to troubleshoot Kia Ceed's engine not starting issue?

I'm having trouble starting my Kia Ceed's engine, what could be causing this issue and how can I troubleshoot it?

First, check the battery to see if it's fully charged. If the battery is not the issue, then it could be a problem with the ignition switch or the starter motor.

Another possible cause could be a faulty fuel pump or fuel filter. Check these components and replace them if necessary.

If none of these solutions fix the issue, it's best to take your Kia Ceed to a certified mechanic for further diagnosis and repair.
