I hooked up a pertronix ignitor, a MSD 6al, a blaster 2 coil and I am not getting any spark. Are there any reasons that might contribute to this?

 

may be you burned out the stock ignition module. Or bad groud on the MSD box

 

check all wires, go back to the basics first and make sure everything is right

usually if no spark, try and find out where there is no spark coming from, coil, dizzy, leads, plugs etc...

most electrical problems are most of the time have simple solutions, if u have a multimeter, use it to it to see if everything is earth correctly, has full 12v etc...
