How to troubleshoot a Ford S-Max that won't start?

I have a 2015 Ford S-Max that won't start. It h������as been working fine all morning but suddenly when I tried to start it after leaving the store, the engine wouldn't turn over. All the electrical components seem to be working fine, so I'm not sure what the issue could be. Any advice on how to troubleshoot this issue?

It could be a problem with the starter motor. Try checking the battery connections to make sure they are secure. If they are, then it's likely a problem with the starter motor and you will need to have it looked at by a mechanic.

Make sure you have enough gas in the car. It may seem obvious, but sometimes we forget to fill up and that can cause the car to not start.

Check the spark plugs and replace them if necessary. Old, worn out spark plugs can cause starting issues.
