Weird coil pack issues
 

I am working on a friends 2001 Santa Fe with a 2.7 liter 6 cylinder. The front coil pack (#1 and #4) is not working. I have 12+ volts to the coil with the key on and also while it is running. I switched out the front coil pack with the center coil pack and the front coil works in the center position but the center coil does not work in the front position. I tried a new coil pack with the same results. I pulled off the #4 wire and the #1 still does not spark. I pulled off the #1 wire and the #4 still does not spark. Anyone have ANY suggestions? Could it be a bad ECM? A bad crank or cam position sensor? This thing is driving me crazy(er) and it is not driving my buddy anywhere very fast on 4 cylinders. Thanks.

Anyone???
