i've got the following codes and the car runs with a miss. its intermittently hard to start. when turning the motor over you can smell fuel. i'm thinking it might be flooding a . but thats just a guess. it has the 5th injector circuit code.

NOW, the car also. has crazy problems that would seem like the bcm, but i replaced the bcm and it didn't fix it. the gauge/interior and headlights do not turn off after removing the key. it is intermittent. and earlier today when i was looking at it. it seemed that if it was runnning okay the lights would go off. but if it was running badly the lights would stay on... i really think its the vcm but i wanted some feedback from the pros

First, I would clear all the codes, and see what comes back up, just to get rid of all the leftovers from the BCM change. Second, I would put in a new ignition switch, as they are known to go bad and cause all sorts of erratic, random issues when they do. Only if that doesn't fix it would I go the vcm route.
Also, could you have bumped/unplugged the #5 injector during your troubleshooting?
