recovery system problem

I am having an issue to where when I try to fire the igniter through the software and it is not firing despite it saying it is ready. I do the arming and firing sequence correctly as well as in I arm and then fire it well before the countdown goes to zero. I'm using the MJG Fire initiator wires...

When using the engines given by our rocket open rocket, there is no problem in the parachute system. Since we are given a different engine in the competition we will enter, we upload its file. When we simulate it acts like a parachute is not added. What do we have to do? Please help me.
