Jeep Information

I have a 2003 wrangler se with the 2.4l I4. I developed an occasional miss and a check engine light. The codes were p0300 and p0302. I changed the plugs and plug wires and the miss got worse. I checked compression and found cylinder 1,3,and 4 to be around 180psi while cylinder 2 was 0. I removed the valve cover and found the cylinder 2 intake rocker arm setting off to the side. I checked it out and compared it to another rocker arm, and found nothing wrong with it so I put it back where it goes and put everything back together. After everything was put back together there is no power going to the coil pack, so I'm getting no spark. I have double checked and had 2 other people check and nothing is disconnected. I'm at a loss and have no idea where to go from here. Any help would be greatly appreciated. Also I'm new here so if there is already a thread for this please forgive me and point me in the right direction. Thanks in advance.
