Default poor mans R injector problems

ok the motor setup is b18c1 bottum with ITR crank, rods, pistons, mated to a b16 head with ITR cams, has AEBS intake manifold, STR throttle body, injen intake, and ITR 4-1 header, Chrome chipped p28 ecu. So my motor is only running on 3 cylinders, 2, 3, and 4. First we'll start with the new parts list. All parts are OEM
-New Distributer
-New coil
-New rotor
-New cap
-New wires
-New plugs
-New headgasket
-New injector seals
-New cam Seals
-New timing belt
-New fuel filter
-New fuel Line
-New fuel Pump
-NO check engine lights, 210 compression across the board, fuel pressure at 39 psi at the fuel filter, Timing is dead on. Has fuel, has spark, trans ground, vc ground, and thermostat ground have good connections

So I start the motor, I can unplug the injector connector for injector 2, and the motor will bog down, then plug it back in. I can unplug injector 3 and it will bog down, then plug it back in. I can unplug inector 4 and it will bog down, and plug it back in and comes back to normal. If I unplug injector 1, the motor doesnt bog down, or change idle or change anything. I can leave it unplugged all day long. But if i do that for 2, 3, or 4..the motor will bog down and want to die. Hince then it would only be on 2 cylinders. So I swapped out the injector 1 with injector 2, cause i knew 2 was working, and tried again. This time, the same thing would happen, 2, 3, and 4 would fire...but still not 1. So this elimiates it being a false injector. So then I have all 4 injectors plugged up, I swap the clips from 1 and 2, since i knew 2 was firing. Same thing, 1 is still not firing, while number 2 cylinder is firing off of the number 1 injector clip. SO this elimates wiring probelms. Now im lost. Im sure this is very confusing to everyone, but i hope someone can help me out. I dont know what to do next. Fuel rail is NOT clogged, it is getting fuel to each injector( cause each time I would pull one out, fuel would come out)

HELP ME

Have you taken the injectors out and tried to pulse them to see if its spraying?

Maybe a corrupt .bin file.

Maybe something in your dizzy not letting #1 fire or did you say you had spark in that cylinder?

Just trying to throw out ideas for you.

What make/model is the car?

Check to make sure the plugs in the injector clips are contacting the plugs in the injector. I had the same problem when i switched over to 310 rc injectors.
