Who built your MS? To run fuel AND ignition with the MS on the 420A, the MS board has to be modded in order to run ignition control. Since we dont use the IAC feature, whoever modded the board may have run the spark outputs on those wires. I suggest to open the case up, and check it out. The two outer LED's on the front of the case, are your spark triggers. Inside you should see a wire going from each of these LED's to the DB37 traces somewhere. You need to "trace" the path of the board's traces from those wires, to see exactly where the spark output's are on the DB37 plug. Make sure you have the CRANK sensor signal wire going to the tach input to the MS, not the "tach" signal wire. Make sure you have "neon" set in the codebase functions, and only that set. This should be a starting point for you.
