Question

So I have a 2005 Nissan Sentra 1.8L Speacial Edition and I got a trouble code P0300. I already changed the spark plugs and Crank Position Sensor the car was running good for about 3 months until the same trouble code came up again but this time the car will not start!! If anybody could help me out I would appreciate.
