Running on cylinders 1&4 only, help!

Running on cylinders 1&4 only, help!
I am at a loss. I changed some stuff up on my car (turbo, cleaned the injectors, new intake, etc.) and now when I start it up, it only runs on clyinders 1 and 4.
I have ensured that it is a fuel issue due to the plugs being brand new and zero gas on them when I pulled them out, swapped coils from 2&3 to 1&4, 2&3 still do not want to fire. What else could it be on an evo?
I tested the wiring for the CAS, and it is as follows:
11.88v
3.78v
.06v
This is with the key in the "ON" position. Are these good numbers?
Thanks for any and all help,
Josh

11.66 Volts (cold outside, small battery) to the coil, Checked continuity for the ground as well, and the third pin is getting .06v as well. I checked all fuses that are maked as an engine fuse in the engine bay and in the cockpit, anything else I should try?

I took "not firing" as no spark as in the coil not firing. How do you know its only running on 1&4? Misfire counts? Did u try swapping injectors around? Do you have access to a scope?

I just checked if my injectors were getting signal via a noid light, and they are both getting signal as well....
My spark plugs are completely dry and brand new looking everytime I pull them out which is why I believe its no fuel, but they are getting a signal to open.
It just seems weird to me that both cylinders that are having the same probelm are on the same coil pack as well...

yeah, everything was perfect before I swapped turbos, it was about 160 across the board.
I just swapped injectors 2&3 (the cylinders that were not getting fuel) with injectors that were in cylinders 1&4 (the only two that were working correctly) and found that the injectors I moved from 2&3 to 1&4 are not working now, which leads me to believe that the injectors are not working correctly.
How do I troubleshoot my injectors? Why would two of them be bad at the same time?
Before I started my car today, it was sitting until September with e85 in the tank, which I drained completely, and also removed the injectors, soaked them in pump gas, and made sure I didnt see any black goo anywhere.
Where do I go from here?
Thanks
