Unless you have actually watched the plugs spark (grounded to the block) while cranking, there's no proof you have fire. My guess would be that you don't have it. Coolant spraying around the engine bay might have shorted something - did you check fuses and relays? Once you get it going, might be a good idea to do a leak down test, just to make sure the HG didn't go South as a result of the overheat.
