What gauge wire?
How did you check the resistance of the wire? Several hundred feet of it or with a real low-ohm meter?
Continuity doesn't count here. A typical muti-meter passes only a very few milli-amps through the circuit when ohming it.
I imagine that the injector peak current is several amps, maybe even more than 10 amps.
Two aspects to this: the +12 Volt wire(s) to the injectors could be unshielded and a nice big fat one. The wire from the other side on the injector to the EC-2 is probably best shielded, but it better be thick enough to carry the current without significant voltage drop. Especially important in your airplane where the prop is on the wrong end :). I guess you easily have more than 10 feet of wore from the EC-2 to the injectors?

Al,
I have two EC2's. Bob White sent me his to test against mine. The NOP is flashing on both and A/B processors too.
I have power to pins 33 and 34.
Spark plug / ignition test on Mode 8 works fine.
2 Serial leads have connectivity between EC and EM.
Since I have a second EC to swap, the EC is not a suspect.
During the Tracy's update I replaced the single wires to the injectors with two pairs of shielded 18 gauge I got at S&F.
I started suspecting the wire, since it has one blue and one white wire inside. The number on the wire is: 2112/202SJ-18 1F2Y2.
I thought it may be a some kind of resistor wire? But we tested resistance, and checked fine?
Thanks Al. Looks like I need dumb luck to get out of this one :)
