2007 Yaris won't start - battery, starter, ignition switch okay

[quistis]

My 2007 Yaris that I bought in 2015 is/was still going. However, on Friday, my car named Red decided not to start after already driving him about roughly an hour before that.

My fiance is knowledgeable on the mechanic end, and he has been trying to figure out what is wrong with Red.

Upon trying to start the car, there is silence - no cranking, - just some dash lights turn on on the dash.

We first hoped it was something simple like the battery, as we did recently have some battery issues with corrosion, but he took it up and Auto Zone said it was fine.

Then he tried/tested the starter, and that turned out to be okay. We are getting power from the battery to the starter.

He tried a new ignition switch, and that isn't it. He has also tested most wires.

The next idea he is trying is an ignition relay, but if that does not work... he is not too sure what to try next.

Any thoughts/suggestions?

Thank you!
