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.
