Intermittent injector 3 failing

[boost97gst]

Basically this started after i got link. It never did it with stock 450s, though i will say i didnt drive more than 200 miles with stock fuel inectors.

I get a cyl 3 misfire code and go lean. Start pulling inj clips one by one and listening and sure enough, number 3 isnt working. Now i havent put the oscilliscope on it yet but im HOPING, like all hell im hoping, that i see no signal and its simply a wire. I sent my ecu in for socketing and he apparently went through it. Par for the course from what i understand of tom. Is it possible for the ecu to cause just one inj to fail?

Im going to wire in some new inj clips thsi weekend and see if its resolved. Just wanted some input or similar stories/fixes.

BTW, same problem on brand new pte 1000s and now flow tested and cleaned bosch 1600s on e85. Didnt matter on the injector.

The harness is trashed though and not placed correctly i believe. Doing a full tuck this fall but id like to drive it til then.

Thanks

edit: Getting powerful spark on all cylinders when code happens. It IS the injector signal. That is very important info

Thought id update. Rang wires from ecu to injector. Good. .6 ohms which is well within range.
Also i found that oreillys noid light kit doesnt work. They are not leds. I put it on one of the know working injectors and it doesnt blink. Tested the light and it works fine. My thought is that its not as quick to turn on/off as an led so it wont light up, or the current is simply too low. idk

Now i test injector box(i know its good but still) then i get to repair the ecu driver. Fun.
No schematics for the ecu either.

Does anyone know where i could find a schematic of the injector drivers in the ecu? Its a 97 non-eeprom but was converted.

I know im going to find a burned transistor, at least thats what im hoping, otherwise if ####ed and have to buy a new ecu which blows.

Ok, resistor pack measures 6.6-6.9 ohms on all 4. Wiring is good. Gotta b the ecu. damn.
btw, injector 3 and possibly 2 are failing constantly. Can start but sounds like 3 cylinders. If i disconnect 1 or 4 it dies quickly. #2 disconnected and i can hear a very slight change but it still runs, on only 2 cylinders!

You ever figure out your problem?
