The ESTA only gives authorization to travel and not authorization to enter. You can receive a reply with-in 5 minutes of paying on line (last time I used it, it took 14 minutes).I can't imagine the ESTA would be valid, so you run the risk of being turned away at the border. Of course none of us know how joined up their system is, so there's a chance you might be OK, but that's a big risk. Up to you if you can afford the loss/disappointment.
The ESTA system makes very few checks as far as I understand. Iirc, it checks booking details and the passport number against a list of people who have been refused an entry visa, deported, arrested/convicted etc. but only on American system.
The USA (at this level) does not have access to the UK police computer. If you are asked at immigration if you have ever been arrested or convicted and you reply no, that's it, they have no way of checking at that point (that doesn't mean they don't know about a conviction via another means).
