How do I troubleshoot my Ford S-Max's engine not starting?

I recently bought a used Ford S-Max and its engine is not starting. I have checked the battery and it seems fine. What other common issues should I look into and how can I fix them?

Check the fuel system, including the fuel pump, fuel filter, and fuel injectors. These can often be the cause of an engine not starting. Also, make sure the spark plugs and ignition coils are in good condition.

Another common issue could be a faulty starter motor. Make sure to check the connections and the condition of the starter motor. If needed, replace it to get your engine running again.

Have you checked the ignition switch? This can also be a potential culprit for an engine not starting. If you suspect it may be the cause, have a mechanic check it and replace it if necessary.
