Car won't turn over

What is your question?

I had a hose replaced that busted. Had to tow car because still wouldn't start. There are no check engine light that comes on. Battery fully charged. Lights work. But it won't turn over. Is there a relay switch or some kind of switch that needs reset? No one can figure out why it won't crank. Does the battery cables need to be taken off? Thought maybe something needs reset. Any ideas
