The cable was wrapped around the washer funny but that shouldn't result in NO shifting, just poorer shifting. Sounds like you fixed that anyhow. Next step is to make sure it's connecting at the shifter properly- double check to make sure the head of the cable is engaged in the shifter properly (kinda sucks since you've got the bar tape done already, but with a flashlight and patience it is possible to feed the cable back through without removing the tape.)
