Logic Probed Harness to ensure correct connections
Spark tested (Finally works)
Checked all grounds
Checked Ohms and voltage on all fuel and distributor components
ECU tested and is good
PROBLEM AND BACKSTORY
Okay so if you have made it this far, THANK YOU! So, a quick backstory leading to the issue. Bought the car late last August, had it for a week and while showing a friend the odd fuel injector setup (See pictures, the casing around the male prongs to connect to the engine harness from the fuel injectors were removed, so it was just open barely connected wires) I unplugged one, started the car, ran rough as expected. Turned the car off, reconnected it, when to start it back up and nothing. So, unplugged injector connector, re-plugged it, no start. So eventually towed it home after a few months, then winter hit (North Dakota) and no garage, so no heavy work. About a month ago it was nice enough to start testing, found 0 spark. Multiple people, multiple tests, Multiple methods. 0 spark in any cylinder. So, I retimed it and no spark, but timing was WAY off so it was a good idea... I think, it ran a little rough but not bad before going out. I then went through and tested my dizzy and replaced the cap and rotor and rotor screw and some other screws within the dizzy. And behold, SPARK! But no start still, what?! Compression is good. So I spray some starting fluid into the intake with a friend cranking, and it was screaming! So I replaced the messed up connectors, nothing. Then the old dirty injectors, seals, nothing. Replaced the fuel filter, now it misfires and half starts for a second and dies, so maybe only 2 cylinders getting fuel? beforehand it wouldn't even turn on its own, maybe one cylinder half fires after 10 seconds of cranking. Pump is good and tested, harness connectors and injectors all read good on multimeters, noid tests and logic probe testing. Now I'm unsure how to test the fuel pressure without a Schrader valve, there's the fuel pressure regulator, and nuts on the fuel filter but no where in the line or rail is there a valve. Fuel is getting to the rail, but maybe pressure is bad? So, so spark is good, electrical all reads good for fuel and spark components. I made sure injectors are fully connected to harness, and sealed well to rail and engine. So, my ideas are new fuel rail and/or pressure regulator or fuel line blockage. gas is from September 2023 but has been treated and looks good in a cup, no chemical testing as I'm not familiar with that and feel with some seafoam it should run, even if it ran rough. If you guys have any ideas what else it could be please let me know. I'm not on a huge press for time, just knowledge. If you guys have any good links to what else to test and how to test let me know! And if you have any warnings and wisdom for this kind of swap, let me know! Thank you all so much I appreciate it a whole lot!!

Where did you get the new fuel injectors from and what type of adapters are you using (slip over the top of the injector and into each hole of the fuel rail) ?
