Check you are getting spark to the cylinder.

Check the spark plug boot is connecting the plug correctly.

Check the plug gaps are 0.028"

Check the distributor cap and rotor for damage and wear.

Check inside the distributor for leaking oil internally.

Last thing, check the cylinder compression. Low compression may mean a burnt valve.

My P0304 turned out to be the #4 injector. I started with the plugs and coils then fuel. Hindsight it's the easiest to check the injectors first.
