Just had another thought on your flooding problems Buly. 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.
If you followed that complex sentence, you will immediately eliminate all
these 'should nots' from your electrical system. It sounds like the EM2 is
one example of something you have on that bus that should not be there.

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.
I restored the factory
settings on the EC2. Maybe I'll start reducing the injector flow in
mode3?
