Im getting no spark to my 4th cylinder, and Im debating what it might be. Any insight>?

Ill check the distributor tomorrow, but Just going to pop out the question so once I wake up tomorrow, so I can get shit handled.

My Dohc ka wont fire up, I can hear the air/fuel when I crank it and I even checked the fuel pump so I know its the spark.

what u can do is take the spark plug out of the 4th cylinder and place it on top of the valve cover with the wire attached dont forget to cut of the fuel when u do this and check to see if there is a spark if not you will know for sure it is spark but also try different spark plugs. well good luck and hope that helped
