The injectors on my throttle body are flooding the engine with gas. Why so much gas coming out of ejectors steady backfire when trying to crank?

Welcome to the forum, check injectors, check fuel pressure, If the injector/s has a constant ground, either the circuit is shorted to ground or something wrong with pcm. Are there any codes? If it turns out to be a pcm problem, there might be an underlying issue causing the pcm to go bad, you fix that issue first. I have also seen one of the injectors short out causing the PCM to give the signal to open the injector full on.
