2006 Tundra AM2 fuse blowing

I have a 2006 Tundra that keeps blowing the AM2 25amp fuse when I turn the key from on to start. The starter solenoid never clicks nor does the starter turn at all.
If the key is at ACC or On nothing happens. As soon as I turn it to start, the fuse blows.
Any suggestions?

 

I know this vid is for a Corolla but the info still applies. Start checking your wiring harnesses. Good luck.

Good vid. I'm confused as to what the oil has to do with anything? Likely a shorted wire somewhere. A harness that has melted and exposed. The relay could be this issue, but probably a shorted wire somewhere.

 

KNABORES,
Did you get this fixed?
I am having the same issue with my 2011 Tundra. My fuse(AM2) is only a 7.5.
Thanks,
