Kinda depends on the yeast and the real reason its refusing to start.. You could have to pitch yeast again, but i dont know if i would do it tonight. I'd probably wait until tomorrow night.
So you pitched 1116, which appears to be a good choice in this instance. It's one of the more persistent yeasts Lalvin offers, able to deal with a wide range of difficult conditions. I would give it a chance to start back up.
