Stop in for a cup of coffee

So happy repairs all around!
And i’m awesome too!!
F150 hard cranking,bucking against starter/ milling flywheel...
Battery weakass piece of crap, didnt fix it.
So instead of using key to crank, i jumpered the starter and same problem. Weakass starter.
Ring gear is good.
At first impression it cranked like it was way out of time. Was thinking it was crank sensor or ecu.
