I have this pull up bar and I had quite an easy time getting to that passing out feeling while on my knees but the problem is that I was like maybe 3 steps away from the door(the pull up bar is at the entrance of the room where the door is) so the noose was quite low meaning what if I move after passing out and somehow move back meaning it would put pressure off my neck. I am afraid that would hinder my attempt. I have tried kneeling right under the pull up bar but for whatever reason its harder to get to that passing out feeling and feels more uncomfortable. I suck at english, idk if I explained it well
So, I was trying to hang myself with an electrical cord. The noose was above where the Adam's apple would be if I were male (I think) and my legs were splayed out like the third person's in the drawing.
My vision started darkening until it was almost black, but then it just completely restored as if nothing happened.
What am I doing wrong? Do I need more pressure? I'm pretty sure that spot is my 'sweet spot' as it's the only one where I can consistently get my vision to darken, but do I need to put the noose somewhere else on my neck?
When you lose consciousness, you'll also lose control of your entire body. You'll be hanging from the rope with your weight exerting pressure.
It's a good idea to use a knot that tightens itself when weight is applied (for example the Noose knot with stopper not, also known as Arbor Knot)
Remember that the knot should be placed at the back of the neck, in the center.
Perhaps the ligature position is incorrect or you are not applying enough weight to block the carotid arteries (and are only blocking the jugular veins) and that is why you are feeling discomfort.

'How to locate the carotid arteries?'
It seems to be said that I should be able to feel a pulse where they are but I can't feel anything . Any tips ?

It's easier to access the carotid arteries with the ligature placed under the jaw. More or less at the height of the Hyoid Bone, which is above of the Adam's apple. You'll find this is the softest area of the neck, where the rope will penetrate most easily. You can even feel the strong pulse on both sides of the neck.
In Partial, the more of your weight you can apply, the better (like standing or kneeling posture)
I also recommend reading AreWeWinning's detailed explanation:

Post in thread 'Is Partial Hanging Actually Reliable?'
I'm very, very worried about whether I'll succeed or not. I don't have a full plan set out, but I'm certain in my decision and have been thinking about it for a while. I am away from my ctb location, for anyone who may ask. Is Partial Hanging reliable? What are the chances I might fail, and how...

About the electrical cord, it would be better if you could replace it with a rope that has a little more area to apply pressure.
