Tracy, with my setup I can not turn on the EM2 without having the masters on (which powers the EC2).
And can not turn the injectors on without the masters.
Having the primary injector CB off the avionics bus helped. It was feeding some voltage to the EM2.
Live and learn?

In the "back feed mode" where the injectors are on but the EC2 is off (this should not happen if the EC2 operating instructions are followed) and If you have some significant load on your 12 line to the EC2 (you should not) that load will look like a path to ground for the injectors AND TURN THEM ON if the load is high enough.

> Thank you Ed and Steve. Looks like my understanding of the f. injection is right. I checked the spark and I'm getting very good spark at the spark plugs, but again they get dripping wet right away, even with secondarys turned off? I'm not using the "cold start" feature.
