Check to make sure both your brake pedal and clutch pedal bumper pads are still in place.

Not sure if any of these links have been mentioned or if you saw any of them regarding non-starts.

There is also this thread where a GT350 owner had a no power non-start issue and could not get the car to start, it ended up being a 125A fuse:

This M6G member had a non-start failure and after much diagnosis, it was found the cause was due to a wiring harness. The harness that was eventually found was under his S550 and it rubbed on the chassis enough that the wear chafed through the outer protective conduit and rubbed through the wire casings causing a short, which kept blowing a fuse. See post #34 of the below thread:

I solved it before I was able to read your post.

I knew it had to have something to do with the BCM, and the fuses were checking good. So I started to figure it had to be a broken wire or a short somewhere that had rubbed through, but as a last-ditch effort I decided to start wiggling connectors.

This connector with a large-gauge white w/red wire was unplugged. My guess is it somehow came loose over the last 6 yr/ 135k mi and I finally hit the bump that was the coup de gras.

I snapped that connector back into place and I’m back in business.

Thank you all for your help and your time to respond.

Good diagnosis and find! It will definitely benefit others in the future with similar non-start issues!
