Update, I managed to get back out today and look over some more.
All doors and windows were locked/ up and so nothing was taken cut etc inside. I did got back through and open /close all the safety doors so everything should be ok as far as interlocks are concerned. I traced the positive cable all the way back to the starter solenoid and have 12v, in the picture below I found something I dont recognize, but i pulled the plug off to check for voltage and on the 3 pins there is nothing.
I visually inspected the cables all the way back and did not find any inline fuses which I was hoping I would. I also followed the negative to the frame ground as well as too the start and everything looks good as well.
I was able to hook up a remote starter to the start solenoid and spin the starter but even with the key in the run position it wont start.
Battery installation still looks ok to me
On the remote start panel (back by the engine bay) I also checked the fuse. the main one i noted was the ecm ign fuse which is getting 12v when the key is turned on.
but really not sure where to go from here. Just for grins I pulled every fuse again and checked. and all were good, And yes the missing ones all look normal to me, there were several that were not in use and the bus was running fine. I appreciate you all looking and the help being provided..
