It's usually something simple, but it can be hard to find sometimes.

Thsts what's giving me a little hope that it's not the motor, since after it sat for a bit it did still try to actually turn over once.

Sounds like either a severely discharged battery (alternator issue, etc.), or a mechanically seized engine. Being that you just had major work done (engine came out, right???), it could be anything.

I’d do what others mentioned, and try to crank it over by hand. If it’s a manual trans, make sure it’s in neutral. If it feels normal and free, then it’s probably an electrical thing. If not, something major failed or came loose inside the engine. With 100 miles since being torn down, that’s a likely scenario.

a multimeter and a load tester will rule out battery real fast. I hope for your sake it is something simple but i'm guessing motor but hard to tell from here.

Do you have a wideband setup on it?
