I had the fuse removed as well, and notice it takes awhile for the start button to respond. It doesn't happen all the time, though.

I've noticed that the only time there is a delay in car starting is when you get inside and wait a while before you push the start button.

You may be on to something. I was in my car this evening, door open, fiddling with a laptop. Thought about your post and waited several minutes (at least 2, maybe 5) before pushing start btn. Pause before starting.

Mine started after I removed the fuse but only sometimes. I noticed it yesterday when it took a good 10-12 seconds to actually turn on.

hmmmm All the other posts I've noticed have reported 1-3 second delays. You may have something else going on.

I thought it was just building up suspense before starting.

Like a good movie.

It's the accumulation of matter and antimatter for warp speed in forward motion before pressing the accelerator.

I too have noticed the occassional delay after the steering lock fuse was removed. Since the delay is inconsistent (most times the car starts just like it did before the fuse was removed) the fact that opening the door and waiting awhile before starting seems to result in a pause when the start button is pushed. I've noticed this once and will attempt to duplicate the conditions. The delay was about a second or two if I recall.

I experienced the approx. 3 second delay today again. Just got in the vehicle and pressed the start button and the delay occurred. Didn't leave the door open for an inordinate amount of time. I tend to think that SCGOLFER7 may be on to something since the BCM appears to send signals to the ECU to verify some of the system checks. This would explain the diagnostic procedure noted in NTB12-041.
Has anyone had a dealer perform the procedure describe in NTB12-041?

I think what you, I, and golfer are talking about is pretty much the same thing - an extra system startup routine that gets executed for some reason. Whether that is a memory purge or a self-check or something else remains to be seen.

I haven't noticed anyone posting about doing a BCM reflash, but I can't read all the posts.

I just read over NTB12-041 again and I can't tell for sure if the two are related or not. The startup symptoms are the same, but I don't remember anyone reporting that they couldn't shut the engine off with an SLU failure. But I've read a lot of SLU posts and may have flushed that particular piece of info.
It would be interesting to find out if they are related or not. If someone has been unable to shutdown because of SLU failure, I would consider that to be strong evidence for.

LMBmikeZ posits that it's the car doing an extra self-check. Sounds reasonable to me, but what is it checking and why doesn't it get checked every time?

probably just going through the usual system checks, checking steering wheel lock and unlocking it, making sure there is fuel in the tank, making sure everything is all good to start without damaging the motor, or ecu delay

its all drive by wire tbh and as much as i like my start button, it just doesnt replace the key-barrel

If you've pulled the SLU fuse your car won't start after 21 Dec 2012.

I was told it would explode if you installed a GT-R button.
