91 GTA 350 all 4 passenger side fuel injectors don't pulse, power on both wires going to injector. if one bank of the ECM isn't firing could there be a fuse blown for that bank and if so where would it be? or is the ECM just fried and needs replaced or can you just replace the one driver board thats fried?

Yes or if one injector shorted will take whole bank down
Disconnect one injector in the dead bank at a time and see if others fire
Check injectors resistance.All should be the same

3 injectors read 16.9 and one 6.9 even with it unplugged the other 3 still don't work

I feel dumb now, inj fuse was blown, i know i checked it once i don't know, I guess that is what i get for working with budweiser thanks vetteoz.

you still need injectors. The one at 6 ohms is shorted. It will keep blowing fuses or fry you ECU,

ya i plan on getting some new ones when i put the new BBK intake on and looking at a turbo that goes under the trunk area in place of the muffler and run the intake up from there rear to it.
