Firing pin cracked

I still don't get how or if at all the spring is ever pushing back on the firing pin.

What part of the firing pin is the spring ever pushing "back" on ?

There is only one coil spring for the firing pin, and it fits into the firing pin's cup at the rear. Inside the bolt, the pin is inserted from the rear, then the spring goes in, then the spring is trapped between the firing pin and the spring retainer, which bayonets into the bolt at the rear. The spring can't pull the pin back, because it is not attached. There is no other spring to push back on it. Even if the pin broke in half, there would no way for the spring to be pushing any part of the firing pin back towards the rear of the gun.
No ?

My comment on the chain-fire phenom was not really to the point of the OP, .... I just threw it in to elaborate on the spring thing.
