PLEASE HELP!

I have a 06 si that I can’t get started, I was driving it one day and all of a sudden it stalled out and never started up again, I have tried so many things, I’ve replaced the fuel pump, the fuel pump relay thinking it was a fuel problem, I just found out the car is not getting spark to two of the spark plugs, I changed out all 4 of them and still get very little to no spark. I was going to change my coil plugs, but I thought to test the wires to make sure they were getting power, and I found that 2 of my plugs were not getting any power while the other two were? I’ve replace most of the relays and fuses and still nothing. I’ve cleaned up the grounds and I still can’t find the solution, can anyone help me?
