3&4 fuel injector wires have no power to them help

[Reedup6911]

So al while back ago posted on help for a no start since then I been doing my tests on my 95 eclipse gst narrowed it down and found two of my injectors 4&3 ain't got no power to them to fire,things that I did was rebuilt the bottom end stayed with 7 bolt motor,new spark plugs,new fuel pump,new battery,bought another ecu from a friend,new starter,yesterday we moved bank 2 fuel injctor wire to bank four in it started n was running very low. rpms weren't even moving,I just need help what to do next?thx for looking

Did you use a test light or multimeter? Was there any voltage at all? If not than you need to do a continuity test from the injector plug to the injector resistor pack. The problem is likely a broken wire from the resistor pack to the injector clip.

I used a multimeter and has 0 volts to bank 4&3 completely dead I will check out what mentioned now thank you!

The injectors get their power thru the resistor so that is a good start. If you find that they have continuity to the plug on the resistor pack than i would suspect that the resistor pack is bad.

I had a CAS go bad on me and cause a similar problem for, give that a look too?

IF you know the schematics of the car than you know that isn't possible. The injectors get a constant 12 volts thru the resistor pack. That is constant and isn't controlled by the ecu.
