Thanks for the info. I'll check the temperature using that method tomorrow. If that's fine I will for sure get another coupler as my next step. I'll update if neither of those things work. I really need to get this fixed sooner than later.

When you took the nozzle apart did you try to pull the sensor out?
I'm guessing that you are sure your nozzle is clean and not partially clogged also
On my UM2, I had suffered this symptom after about 200 hours print.
The cables for the temp sensor where not sufficiently connected to
the PCB.
My heated bed would not always be hot, so i opened up and the screws in the
green connectors on the PCB where very loose.
The connector for the hot end temp sensor was almost falling off ...
And like Monsieur Klein says, Teflon! If youve printed ABS it is cooked for sure.
Even if it looks ok-ish it will collapse and grip the filament under pressure.
Loosen the 4 long vertical screws a bit too, I learned from the veterans here..

Yeah My nozzle is extremely clean. I cleaned it out several times.
I tried to pull the sensor out when I had it all apart and it is for sure stuck in there.
My teflon coupler looked pretty bad and I had trouble trying ot push filament through by hand. I will replace this for sure regardless of if there is anything else wrong.
Is there anywhere to order parts in the US? I know they can probably get me one, but I kind of need to fix this faster than waiting for an overseas part.
Thanks for the info. I have literally never really had any issues with my printer up until now. I had a couple clogged nozzles but that was easy. This is getting frustrating.
The main fan on the back should be on all the time right? Cause mine is off. and I am never seeing it turn on at all.
The back, middle fan should be on always.
It is hard connected, no PWM here.
Thanks. That's what I thought. I ordered this one just to get it her fast. I can't wait for support to help me on this.

Thanks for all your help.
While you wait, check the wires's connection to the motherboard.
You read my mind and I don't know why I had not checked this before. One of the leads had come out of the connector right above the print head. The fan is spinning away now! I am hoping this was my problem the whole time. Putting it all back together now.
Thanks again!
So gratifying to be able to help!
Thank you!

Hi,
You can check if the temperature is good or not with this method:
Otherwise, i would think that the Teflon could be the cause of your problems (the white plastic you drilled). You can contact support and ask for one Teflon coupler. They might even send it for free as it's now considered as a consumable part.
