Engine Still On With Out Key

[MiNdHaBiTs]

i turned off my 2005 Tahoe last night and the engine was still running. I had to disconnect the battery and alternator to get it to turn off. Today same problem but i was able to disconnect the PCM fuse to get it to turn off.

Any ideas?

wrong forum, but i'm sure someone can help..
have you tried removing the ignition and taking a look at it? have you tried your spare key (if you have one)?
