Have you tried jumping or charging battery and re-testing? I'm just thinking about a failed Alternator causing a battery discharge while driving , thus leaving you with a dead battery.

So in short I would like you to determine we are working with a fully capable and charged battery.

Hello and welcome to JustAnswer!

There are many possible causes for a no start conditon and it's going to require some testing to determine what is going on. The problem could be the starter itself, ignition switch, the transmission range sensor, wiring, a cble or connection issue, the engine controller itself, a security issue, or it could definitely be a battery issue.

Is there any noise from the engine compartment when attempting to start the engine?
