If you have power at the red 10 gage power lead, a good 10 gage ground (good battery???) check to be sure that there is power at the switched source for the small 16/18 gage red wire too. If you have power at both there is nothing on the phone that they can do for you. Their Website
www.msdignition.com has their complete trouble shooting guide on it.
As Clois experienced recently many of the issues with MSD installation turn out to be something simple thaty is overlooked.
