Car is not getting spark.....

There is no spark in cylinder #2 and #3 basically if you look at the engine the farthest left #1,#2,#3,#4 farthest right. #1 And #4 gets spark nothing out of #2 or #3

So basically check in this order?
Spark plugs
Coil packs
Ignition control module
Crank position
Am I missing anything?
