Default Cranking issue

I can't get the car to start/crank in 1st gear while the clutch pedal is pushed in, but it fires right up fine in neutral.

Is there some sort of switch on the bottom for the clutch pedal that could have went bad that prevents the car from cranking in 1st?

Nope. Only one clutch switch, and has nothing to do with gear selection.

That is pretty odd if it really will only start in N and not first. You have tried over and over in first or is it intermittent and could just be coincidental? I have seen starter failures, could be a place to start. You can check the clutch safety switch if you put a test lamp on the start purple wire while someone attempts to crank for you.

So if I am reading that schematic correctly - on the theft deterrent relay:
Red is B+ hot at all times
Yellow is 12V+ that goes through the clutch pedal switch?
Yel/blk is 12V- that is normally closed to ground unless the BCM opens it because of VATS? Or normally open and the BCM closes it when the resistance is correct?
Purple is 12V+ output to starter.
