Why won't my truck crank but makes a humming noise? on 1998 Chevrolet S10

I tried to crank my truck, it attempted to bust over but didn't. It made a loud click and now it just hums

Are you saying the hum is happening while the engine is turning, or the engine is not turning and it just hums?
The engine will not turn at all
That sounds like the starter is bad, or the engine is locked up. Can you distinguish if it is the starter humming, does it sound as if it might be turning without turning the engine, or could it be the starter is engaging the engine but straining to turn the engine but the engine won't turn. Also try to turn the engine by hand or manually.
The engine will turn, it's the starter humming. Thank you for your help, it was a loose wire on the starter
Ya Hoo; Good job, time for nite nite, as my grandson tells me. Good Luck.
