did you check for power at the coil? did you check more than one cyl, also make sure that you dont have spark from the coil to the spark plug wire, then from the coil to the coil wire. you may have tried all that already but just trying to cover the bases.

If the car was running fine then just won't start its your TFI module. I've had a couple of those go out, its very common. Idling in line at the bank it just died, stopped at home for a second and it wouldn't restart when it was just running perfect. I kept 2 extra modules in my glove box with the tool to change it.
