Chevrolet Repair: k1500 no spark

Question
hi tom its me again, i checked for voltage at the coil while someone turned it over. there is no pulse. the plug that comes out of harness has 12v with key on. the other other that comes from the module does not pulse when i turn it over. now this feed wire you speak of. this is the one that comes out of the harness into bottom of dist. to the module i think. you say it should have 12v key on?

Answer
