Based on the spark issues you were experiencing, I'd suspect the "blue" exhaust was really more of a gray-black due to a misfire and unburned fuel in the exhaust stream. Did the exhaust smell like asphalt or like raw gasoline? I doubt the ECU is the source of the no spark, it's probably more like a bad camshaft position sensor (CPS) or possibly a crankshaft position sensor (CKP). When you installed the new distributor assembly did you need to transfer over the CPS/pickup or was that also new?
