Injector ohm readings
My injectors are reading from 3.6 to 17.1 ohms. I know that means its time to replace, but can having the ohms readings all over the board cause the injectors not to fire at all?

Yes.
Low resistance basically overheats the injectors driver in the ecm and shuts it down.
When u kill power and cut it off they cool down, then it will refire until it gets too hot again.
Anything below 12 is junk according to GM.
Most stock injectros I have ohmed personally on our cars were high 16 low 17 ohm range.
Junk them and get some new ones.
