Alright so I’ve been trying to get my car to start and I’ve done a lot, what does it sound like my car is missing now? I’ll add a video, I’m just lost

I’m not using any tuning software, I have an obd2 car scanner that I can see the data on my phone.What tuning software are you using?
I have not done a compression test but I can, but I put new spark plugs in the car yesterday and it still sounded the same, all cylinders were dry except cylinder #3 which had some unburnt fuel from the spark plug fouling. If it isn’t the car misfiring what could it be?Maybe, but it sounds like it's missing to me.
Have you done a compression test lately?
I’ll need to get a leak down tester, but until then just fiddle with other stuff, I’m not sure why it started making the sound though because it wasn’t sounding like that not too long ago and then it just started sounding like that so I’m just trying to wrap my head around why.Next step is leak down test to verify what’s causing low compression on that cylinder.
What should I look for? When I had both 3 and 4 unplugged nothing changed and it made no difference when I plugged them back in.That’s a good way of narrowing down the problem cylinder. That means your misfire is on cylinder 3. Not necessarily that it’s caused by the injector.
If the injector is plugged, it will still click so the best "test" is move the injector as you said @Dericshuse a stethoscope to try to hear if the injector is operating (or trying to). Lastly you could simply just swap it with one that did make a difference when you unplugged it and then try your test again to verify the injector is bad/clogged and moved locations.
