Hi, did you arm the primary timing chain tensioner after you set your valve timing? You have to pry against the guide to arm the tensioner so it springs back. I usually just replace the tensioner, they are a common failure point on a 2.7. If you didn't arm it, the chain probably jumped and would explain the no spark.
