Did you ground the spark plug to metal while watching it? Test light on an open connector won't work. It has to be pluged in, spark plug tighten in the hole for you to see a light. Stick a needle in the wire and attach the test light to that.

Sounds like you've melted or damaged something electrical along the way. U sure everything is plugged back into the right place? MAF connection is good?
