Buly,

If reseating the connector = doesn’t help, it may be good to check the ground continuity between the EC2 and = the airframe ground. It is possible that the amount of current needed = to trigger the ignition coils is significantly less than that needed to = operate an injector. I don’t know how much current the ignition coil = signal takes, but each injector takes about 2 amps. To be certain the = ground is good, one may need to check all the way to the ground plane on the EC2 = board.

Hopefully you will have things = working before you read this.
