Code 12, 14, Anybody know how to repair connectors or where to get new ones? Options

I've had problems getting my 1994 5sfe to start lately. it started a couple months ago, it would randomly not start for a few minutes but then would fire right up.
I have a headgasket leak and so we assumed it was coolant getting into the cylinders, as it would often only do it first thing in the morning and be just fine the rest of the day.

but lately its gotten to the point it doesn't want to start at all. for a while it would always crank up and fire, when it was cold it might die the first couple of times but would always fire right back up. I would keep it at a high idle until it warmed up and then it would be fine.
then I started getting CEL 12, and 14. so I went to the salvage yard and found a nice ignition coil, distributor and Igniter. in fact the coil is a Toyota that not only ohms out, but looks good too(not burnt). my old coil ohmed out right but had a big split in it. I also picked up 2 different igniters(they're small and fit in my pocket).
and when I put it together it fired right up and worked just great for a couple of days but then began doing it again. I took the dizzy back and picked out another one and it fired up the first time but then died and won't start again. I'm betting that first thing in the morning ill be able to start it up, and if I keep it at high idle until it warms up it will run.

granted im getting distributors and igniters out of pick-n-pull, but I just need to figure out for sure What really needs to be replaced before I go buying brand new ones.
from the codes it's giving me it could be any of those parts or the ECU itself. I have been checking the ECU pins with the volt meter of the ones that I can test with the ign ON. but I have not conclusively been able to prove that it is bad.
tomorrow ill disconnect the plugs and check resistance readings from the ECU plugs to check the wires.

code 12 says - No "Ne" or "G" signal to ECU - check distributor, ECU, circuit wiring, and Starter signal circuit.
does that mean the Circuit Opening Relay could have something to do with it?

code 14 is _ no "IGF" signal to ECU - check igniter, ignition coil,

granted the headgasket is pretty bad, if the motor is cold and I crank it but cant get it to start there is already pressure on the radiator cap just from Trying to start it.
If I do get it to start tomorrow I'm going to stop-leak it just so I can eliminate the lack of compression from my problem.
I think though something else electrical has actually failed.

any Ideas? ty
