You are not wrong, the after treatment injector was leaking like crazy. Now that I think about it, I didn’t bother to check everything else when I replaced it 3 months ago (it became a ticking bomb)
I was getting de-rated and as soon as I replaced it I was so glad to go back to work that I forgot all the aftermath it was gonna leave behind.

So here is a recap of all!

When the truck wanted to de a regen or if I waned to force one it would not complete and a lot of white smog would come of the exhaust. DPF inlet was getting to almost 2000 degrees

Aftertreatment injector will not affect fuel rail pressure. You have leaks or fuel pump head, or fuel rail valve, or injector(injectors). Start with fuel rail valve it's most common. If valve is leaking and you install new from Cummins check it too. Today have one new installed and valve is leaking. Not so much as old but anyway.
