I did check fuses with light. All are good.
Have you inspected the wiring directly under fuse box?
I’m wondering if maybe the fuel shut of valve didn’t shut down.
That is usually an impact activated switch.
I read there is a neutral safety switch which will shut everything down, have you heard of this?
A neutral safety switch will prevent the starter from turning when the transmission is in any gear other than Park or Neutral.
Also, how do I find the fusible links. I thought of this but have no clue where to go with it.
You will need a power distribution diagram for your specific vehicle in order to locate them.
