This could be a simple matter of disagreement between the pull up or pull down resistor on the pin and the way that it's wired. Long years ago now we had a similar issue with the NIST hexapod when DaveA showed it off. The extra parport pins had no pull-up resistors. We used an external +5 volt supply, added the resistors, and the extra two motors started going.
Like Manfredi and several others have said recently, HAL is most easily discovered and manipulated while running. I use halshow but then I wrote it because I like point and click. If you get a configuration that will start up, halshow can let you look around a running HAL and allow you to test connections. When I first tried to build a run button, I got it connected and then "discovered" that it kicked up an error message if I pressed it again while a program was running. I got round this problem by adding a ladder rung that said, if halui.mode.is-auto and halui.program.is-idle -- pull program start pin. I could imagine adding a bit more logic to that run switch by making the same button signal a feedhold if the interpreter is running, or release feedhold if the interpreter is paused. This would take some additional testing to verify.
