thanks everyone for your help, I ended up diving into the fuse block a little deeper like Nissanh suggested and found that the 120amp bussman fuse for the alt was fried. once it was replaced the truck started with no issue. crazy how that little thing can prevent an entire motor from starting
that is a possibility, I went through a couple days ago and cleaned all of the grounds I could find on the truck, the alternator ground had some oil and road grime on it. I cleaned it up/sanded it to get bare metal and put it back on
I'm the son.
To give some more information, I have checked all of the fuses, replaced the park neutral safety switch. I still need to verify it's good and properly adjust it. To add to the problem list, the windows in the vehicle don't work, climate control doesn't work, hazards work but not...
