Was able to do some testing of my thermotime switch tonight hopefully my explanation below is clear enough. I removed the switch from the car and tested on a bench.

Large terminal on switch = red black wire on car (this grounds the CSV)
Small terminal on switch = yellow wire on car (power at cranking)

I grounded body of switch and connected my test light between large terminal of switch and + and my Test light comes on.

With the above still connected if I apply power to the small terminal of switch my test light goes out immediately.

So this seems to indicate the switch is bad. Shouldn’t my test light stay lit for approximately 3-5 seconds when I apply power to the small terminal? If I’m understanding this circuit correctly with the CSV then when my car is cranking at startup my CSV would not have a ground and thus not be giving my car the extra shot of fuel at cold start right?
