tested the compression on my 1985 mercury 90hp inline 6 125-120 on the 5 I could test, but now I have no spark.Did I hurt something by not grounding my plugs during test ?

I hope you either turned the kill switch off or grounded the plug wires if you pulled all the sparks out while testing the compression. Some people belive you can damage the stator or switch box because the electrical system can back up and cause problems.
