06 prius: No warning lights, accessories turn on but won't start

Hello fellow second gen owners! Help needed and appreciated!
Long story short she (my prius) was sitting for quite a bit due to her overheating issue (blown head gasket) and not finding an inexpensive mechanic. Finally found one and got her engine swapped but I haven't gotten her to start. I charged her hybrid batteries and got a new 12 volt. The image with the warning lights on the screen was taken a couple days ago and the one with none was tonight. (I've always had all the yellow indications on, she comes with some baggage) Turns out the black terminal that goes on top of the 12v battery was missing the fuse. Now I get no warning lights, no codes (none before either), no ready sign and no speed indication number. For those who might wonder, yes the orange plug on the hybrid battery is in all the way. When I turned her on after inserting the missing fuse her battery showed multiple blue bars, but now just the purple. If I hold my foot on the brake and keep pushing the start button I get cold cranks (hybrid battery clicks) but nothing that starts her up. I will be looking at fuses and taking apart the inverter converter this weekend to see if they put it back together wrong, other than that I am at a loss. If anyone knows anything I would highly appreciate it! I have scoured the internet and have found nothing.
