94 LS high compression n/a motor

I have fuel pressure, i have spark, swapped distributors and still i have one cylinder not firing.

Any ideas?
yeah check the cylinder for compression thats giving you problems. if it it has none then it 1 of about 4 things
well your injector on that cylinder could also not be firing
do a compression test and if one cylinder has no compression try putting a little oil then retesting that will tell u if its rings or not
Also swapped injectors and connectors around and still the same cylinder wont fire.
Bad wire, too. Bad contact on cap. Cylinder gremlins clogging it up.
put a grenade in the engine bay, shut the hood and run away. then you wont have to worry about it any longer.
