So finally got it to actually start after my starter install by replacing the fuel pump but now stuck on this. It will only run with the gas pedal. Spark plug is a lil dirty but looks good cars probably running a little rich. Tried with multiple coils I got from the yard. Any ideas where I should check. Fuel or ecu?
Also what that high pitch sound.
Couldn't post the video so there's a link.

The high pitch sound is a belt or your alternator. I would try to take the serpentine belt off and run it like that to see if it starts without any noise. It sounds like an exhaust leak, did you maybe switch some plug wires by accident on the distributor? or take it out to do the starter for any reason? It sounds like your timing is off, exhaust leaks. try to get another video from the engine bay with a friend starting the car.

a bad ECU will cause these issues as well. I would get to the ECU and take the cover off and just look at the circuit board you can usually see any problems even with untrained eyes. But check out youtube you sound like a DIYer
