I have a 1990 300zx TT and it started driving pretty terribly....it was sputtering and had a hard time idling, eventually it stopped running altogether...I figured it was the spark plugs since i knew they were old...bought new ones..put them in and i still get the same thing....wont start

Make sure you got fuel pressure maybe its the camera but it sounds to me like its got no resistance when you crank it makes me think no fuel in the chambers.

Im getting fuel to the cylinder, i tested the plug outside of the cylinder and im not getting any spark...im pretty sure its not my coil packs cause i don't think all 6 would fail on me at the same time...definitely electrical, but i dont know past that

First step should be to pull the codes from the ECU. Do a search for the procedure and the codes. I'd bet that you're getting a code 13, faulty coolant sensor. You can also pull the coolant sensor plug on the front pipe, and clean the contacts well and try it again. Common issue.

Looks like your belt tensioner is shot or you broke your timing belt. From your first video it sounded like only the crank shaft is spinning. There should be some drag on the engine when you crank it. You found your problem. Lift up on the belt to see if its comes out if its broke or pull your crank pulley off to remove that lower cover and you will be able to see what happened.

If the crank was rotating separate of the camshafts, you might have hit a valve with a piston and damaged it in some way.... Definitely want to look to replace the belt and most likely the tensioner. Just hope you didn't strike a valve with the piston...
