No Spark? MS1 v3
 

Been trying to make this work gone through all manner of things from swapping leads, reversing settings on wheel decoder (tuner studio) etc.

I brought a ECU from extra EFI. I have made a plug and play/standalone loom, it powers up all the readings are correct, i get an rpm.

Finally after taking plug out and laying on cam cover there seems to be no spark (well upon cranking for a few seconds twice only saw one spark.

Is there a way of testing the spark output?

Is frustrating as everything else about it is working, soooo close to running :-(
