Yes,
That is correct the trigger is in the Dist. But, if you have a MSD Dist it should be magnetic, and these are pretty bullit proof! It almost sounds like a wire(ing) problem. I am not sure if you have tried this, but here is the link to MSD. They have a check procedure to validate your components are working fine........
Hope this helps,
