There are only two possibilities, the ignition switch as previously mentioned or a short between unswitched 12V+ and the ignition circuit (possible but rare). Another quick test would be to remove the wire from the IGN terminal of the switch and test for 12V+ at the coil+ terminal with the battery switch on. Test=yes=short somewhere, test=no=bad switch.

Another side effect of this problem is the possibility of coil damage. They don't like to be energized without the engine running and unless you've been religious about immediately switching the power off to the engine system after flooding the engine to die, the coil has been stressed. They don't cost that much, after resolving the ignition switch or short problem I'd recommend a new coil.
