If your starter is bad try to hit it with a hammer as someone turns the key in the ignition. If it starts then, you know your starter is going out.

I’d check all the wiring & fuses/relays.

Jump start the car. If it runs, then you have a weak battery. If not, as the above comments said, you should check the fuses and the starter. 

1. 2002 V6 XLE Camry, no codes thrown when checked. Car was fine the day before, went to go turn the key the next day and nothing.  No engine turnover, no starter click, no trying to start the engine. The battery wasn't dead as the ac and radio and lights all worked. When the key was turned there was a very slight buzzing sound, almost like electricity moving somewhere. Anyways, please let me know if I can get this running without needing a new starter!

Hey all, I really feel like we might need Scotty for this one. We just got all new coils and plugs for our v6 Camry. One of our old plugs was literally in pieces and the coil was melted and another spark plug was as black as a tire. Anyways it had just gotten back from the mechanic 1000$ later we drive it home. After its been at home I was gonna go to the gas station, I start it up and it runs like complete shit, popping and misfiring, then I shut it off and it wouldn't start again. It has a misfire code on cylinder 2,3,4,5 can someone please help explain what it could be?

Have you checked this?
