No Spark
390 in a 75 f-100. Ignition module tested and good. Swapped out the coil and no difference. New ignition switch. Getting fuel but no spark. No clue as to what to try next.

Is there juice to the module?
If you start with no juice at the plug, you have to track back till you find electricity. Then you've got your problem point usually. Don't skip components and check wires and grounds along the way.

I dont see where power comes into module by looking at schematic. Is it the lead coming off the I post on solenoid? Which wire going into module do I check? My module is the one with the blue bracket at wires if that helps.
