How do you troubleshoot a Ford Focus that won't start?

I have a 2015 Ford Focus and recently it has been having trouble starting. The engine sputters and makes clicking noises when I try to start it. I've had the battery checked and it seems to be fine. What could be causing this issue and how can I fix it?

Based on your description, it sounds like you may have a faulty starter. It's also possible that there could be an issue with the ignition system or fuel delivery. I recommend taking your car to a mechanic for a thorough diagnosis and repair.

Make sure to check your spark plugs and cables as well. If they are worn or damaged, they could also cause starting issues. Replace them if necessary and see if that solves the problem.

Another possibility is a clogged fuel filter. If it hasn't been replaced in a while, it could be restricting fuel flow and causing starting issues. Have a mechanic check and replace the fuel filter if needed.
