Where do i start so i can clear this list up?

Start by clearing all data and see what sets with KOEO. Any codes now?

I've never seen a car with anything close to this many codes without some trauma or major repair work causing it. Is there some backstory here?

The aldl reader im using cannot seperate current from historic and cannot (or i cant figure out how to) clear codes and with its current setup the lighter port that powers the reader only works when key is on so a koeo read is impossible right now.

Disconnect the battery for 10 minutes.

The scanner should have the option to clear codes.

Check your battery and cables for tightness and corrosion, and have your charging system tested. Unstable power absolutely messes with electronics, and freaks stuff out big time.

KOEO stands for “Key On Engine Off” and performed with ignition turned on but engine not running. Generally this test is sufficient for detecting problems with electrical circuits. KOER stands for “Key On Engine Running” and performed with engine running at normal operating temperature.
BTW, what brand & model scanner are you using? Is it a dedicated OBDl reader, or is an OBDl-OBDll capable reader? If that scan is accurate, it looks like the ECM had a major brain fart!

This scanner.

Droppimg a new alternator in it this weekend, it will only reach 13.6v and i know thats lower than it should be.

That'* not a scanner or code reader. All it does is short the ALDL to flash the codes. You can jumper those pins on the connector and read them through the CEL. You got ripped buying that thing.
