I don't bite, all that often...
It really depends how on how clean the filter was. It it was near spotless, it may be ok, but 24 hours without flow is not going to be good if there is a lot of debris in the filter...
Either way, when the filter is up and going, I'd do a weeks "proving" with ammonia to show that it is still cycled
This is where you charge the tank up with Ammonia to 4ppm and check it will drop to zero Ammonia and Nitrite in 12 hours or less 
IMO, the best way to fish-less cycle is with Ammonia, purely as you have more control over the process. Either Ammonia or food will work though
