Did this start immediately after you pulled off the upper intake manifold and reinstalled for the injector job?
Maybe a wasted vacuum line? Bad injector connection?

No it ran pretty good after replacing injectors but it didn’t have enough power so I looked at the other bank and found a cracked injector so I replaced the other bank then put it back together then when I tried to start it, it wouldn’t and that’s how I found out that the relay was bad

My credo
Deengineer until it is how Blue Oval should have sold it!!
Shokie:

Were all 6 injectors replaced, exact same brand, model and flow rate?

If I pulled and replaced an injector bank, then had problems, the 1st thing I would do, is check that bank of injectors. I would pull them, inspect the harness, connections/pins, donuts, caps and how well the injectors were seated; then carefully reinstall them.
