Plumbing – No water flow after closing and reopening shutoff valve

plumbingshutoffwater

My faucet was in need of attention so went below the sink, shut off the valves, unscrewed the supply lines, cleaned the faucet put everything back and now the water won't turn back on at the valves. It's not the faucet.
Any ideas?

I have found on old valves the valve stem separates from the gate. they close fine but then it feels like it is opening but is broke. You will probably need to turn the water to the house off , bleed the pressure off and remove the valve and install a new one.
