Fuzes are easy to check. Same with the solenoid. Pull wires off the solenoid and jump it straight to a battery and see if it bumps. Both those should take 5-10 minutes tops in the driveway on the ground.

So I took the starter out and one of the wires was completely busted, got the new starter in and I'm waiting for it to warm up now

Do you have an aftermarket fuel system ? 

So just a week ago I replaced my starter. Yesterday morning I went to start my truck, and it died. No huge issue, happens in the cold usually every morning. I prime my fuel filter and it starts up. That night I go to start it again and it won't turn over. Then as I'm cranking I hear a loud pop under my truck and now won't even click. Any idea what it could be? I don't think it's the solenoid, could it be a fuse? Any help would be appreciated.
