Thanks for the advice. I was trying to lube them with spit, but it wasn't working, LOL.
Ended up separating each injector from the fuel rail, then lubed the o rings with dish soap. They eventually went in. I then installed the fuel rail, this is not the way I have dealt with the injectors in the past, it has been easier to leave them on the rail. Maybe the new delete plates and the cut in the aluminum was the issue. Lesson learned.
