2011 Toyota Camry won't start but I hear a clicking noise when I attempt to start, what's going on?

There's a few possibilities. First, take a volt meter and put it on your battery with the engine off. If you are getting lower than 11.8 volts, it may be time for a new battery. If battery tests fine, I would then remove my cables and clean the battery terminals and grounds. If still not starting, it may be your starter. Have someone hold the key to the ON position like they're starting the car. As they hold the key, you rap on the starter with a hammer. If the car suddenly turns over, it's time to replace the starter. Try these things and post back with results.

I have the same issue, battery tests good, starter is good (replaced with new and the new still doesnt work, then hotwired the new starter and works fine) I can feel the relay clicking when the ignition keys turn. Still will not start,,

I test the battery is good , pump gas is good, starter is good,spack plug also good.
