ANOTHER UPDATE!
I found the root cause. When I pulled apart the front end I removed something that I thought was an airbag sensor... A ceramic horseshoe... Well turns out that'd the fuel pump resistor for the low voltage circuit.
So after a minute of running the pcm says "okay things look dope and we're at idle so let's use less fuel" switches over and... Missing resistor means the circuit was open.
Hooked up the resistor, repinned the relay, and she ran like a champ for five minutes.
Now to replace a dead coolant temp sensor and maybe my fans wills switch on so we can finish this exhaust and these brakes.
