Nice work on the testing. So you feel good about the TPS and found the fuel regulator getting in the way which might be a perforated diaphragm or worn diaphragm spring. 32psi is where it should while running. Book is 32-34psi. Since the fuel pump draws a decent amount of amps the connectors are probably also melted/burned as is normal. If you replace buy some new pigtail connectors.

So.. new pump comes in the mail, I remove sending unit and discover that the pump had been replaced once before and the plastic accordion line is mangled on the ends with hose clamps. I guess that explans why it wouldn't hold its prime. And probably why the psi was low. I'm headed to the parts store now to get some high pressure line to replace the oem stuff.

Ok after replacing the pump and lines inside the sending unit it will hold pressure after shut down. But..... I'm still only getting 26-28psi at idle and it's still not smooth. Pressure regulator?
