First off…. STOP firing the parts cannon.
If you truly feel the need to toss money away, PLEASE feel free to toss into my pocket any time you feel the urge.
Obviously, all the parts you’ve already replaced solved nothing.
So lets try another route.
DIAGNOSTICS.
You have blanket misfires on all cylinders.
So it is safe to assume you have a global issue.
Now it’s time to see what will affect all cylinders.
Fuel:
Do you have the specified pressure at the fuel rail?
Need to test for that, I’m fairly certain there are YT videos explaining it so I won’t have to.
Fuel pressure regulator:
Again, need to test it for proper operation, again …fairly certain there are YT videos explaining it so I won’t have to.
Vacuum leak:
Again need to test for that, same applies for YT videos
Ignition timing:
Need to confirm all your timing marks, inspect the timing belt for any possible damage or jumped timing.
These are the simpler items to check.
From there it will get more intense.
