2000 Pontiac sunfire 2.2 liter OHV already changed the coil pac, coil module, and crank sensor and it still says engine code 301 What could be the problem?

Thank you,

How do you know? Did you visually check for spark at the plug in question? Maybe bad plug wire? Maybe no compression on that cylinder. One coil fires two plugs, how about the companion cylinder?
