No Spark.

So.... I got the battery back, hooked it up... and... I have spark from the ignition coil and at the spark plugs. I guess this is a good thing, but I'm scared that while I was mucking about in there i jostled the magical wire that will curse me until i buy a new wiring harness. Thoughts? Also I didn't really try but it wouldn't turn over. It wanted to but it would stumble and all the lights would dim.
