Default 2006 GS430 wont crank no start

The Lexus died while I was driving out of nowhere while the wheels were still spinning. We diagnosed it to the starter which was genuinely dead along with the battery fro. It sitting so long. Both were replaced. When I try to start no crank happens and the dash lights don't turn on. Power turns on for 1 second which allows the steering wheel to attempt to move and to move any windows. All lights and GPS work but audio and ac controls dont work. I double checked all of the sensors to be extra careful and to not break any. I also can't run a scanner as the car wont turn on. I'm blowing my mind over this car!!!

To me it sounds like the alternator if anything is bad. Because you mentioned you were driving and the car died, and so did the battery. While you drive the alternator is what feeds the battery. If the alternator goes bad eventually so will the battery, some batteries get so drained that a jump start will not even suffice.

I would put a volt meter to the battery and test to make sure that it is fully charged. If not charge the battery fully! Next I would inspect the battery terminals and cables to make sure they are not corroded or rusted out. You can test the power to the alternator as well. Have you tried jump starting the car with another car after you replaced the battery?

Also check fuses (ALL of them)

there's some under the hood, inside cabin, and trunk.

They might have blown when they were being strained under heavy load while u were driving, causing everything to die and not start.
