Jeep wrangler coil pack problem

I have 2001 Jeep wrangler (6 cylinder). Engine started to idle rough and check engine light came on. The code was cyclinder 1 and 2 misfire (primary and secondary coil). I replaced the coil rail. The codes are now cylinder 1 and 6 misfire. I changed plugs in 1 and 6, but no help. I checked resistance on the 4 four pins of the coil rail, but they all show shorted together. Any ideas.
