93' Chev 3500 dually w/454, isn't gettin any fire (spark),any suggestions/ideas?

Hi there, I am not a mechanic but my 97 pickup was not getting any spark and my father in law (a mechanic) told me to put a new ICM (ignition control module) in it. It was a pain in the butt because it is located back next to the coil pack and dist cap. I had to put my dogs bed on the motor to lay down and a inspection mirror to see it. It fixed the problem. make sure you use all of the anti heat grease that they include with the module. I hope this helps and good luck.
