mine ended up being the fuel pressure regulator. I swapped the pump and inline filter out on wednesday and it ran a little better. I nearly torn what little hair i have left on my head out after the starting issue came back a day later. On a whim i noticed the vacuum line to the FPR was kinda nasty and I was out of rubber hose so i used some clear hose for a small engine. Fuel was seeping out of the FPR and into the intake manifold. swapped it out, sucked some seafoam into the manifold and let it idle with some revs for about 20 minutes. Runs great. Now just gotta fix all the rust holes in the exhaust so i dont sound like a mud truck rolling through Memphis
also, take the IAC valve out and hit it with some carb cleaner, should do the trick.
