"All tge electrical worked"
Is this a typo? Are you saying that the electrical "works now" or "worked before" ?
Are you getting any clicks at all from your alternator?
Have you taken an electrical test-light to each of your major connections?
How is your fuel transport? What about the rest of your fluids? Are they frozen?
Do you have any guesses about your engine being seized?
Kind of difficult to guess whats going on, when not actually looking at it, and that you've already done so many swaps to it.
I'm not going to say, troubleshoot some more, but..
