Man this ones a screwy car
Well I'd hate to say this because it will hurt and give you a buzz if it does give spark energy, touch the screwdriver while its in the plug connector with the back of one of your fingers and try to start it, if you get a jolt well OK its getting some. But I would keep trying the other way :D , umm well here's a question, OK where was this thump thud etc. it might, now not saying but might have disconnected something under the dash. But if you try a spark tester which you could rent at auto zone I believe not sure or use a electricians electrical voltage tester/ meter and see if you get something, cheapest way would be above. :D but not recommended. Or could be the belt slipped, not sure what type belt now I'm used to timing chains, could have slipped if it's a belt, not sure on these japanese cars but could have slipped. Like I said try taking the plugs out and leaving them connected to the wires and try to start the car and look for spark and see if you get it in all of them and they are all sparking one after another or in sequence if the starter turns the engine over fast. May have been a computer chip has fried, had that happen to a caprice one time, got fuel and through the injectors and turned over but no spark and the computer was screwy, not saying that yours is though, damn this ones kind of a screwy car, seen one honda crx hatchback going at 60 for 5 minutes and the power steering would go dead. Just screwy stuff, try the plugs though :)
