This is a DIY How To for fixing the Prometheus lighters out there with a no spark issue.  I don’t guarantee this will fix them all but I see this reported nearly daily in the CO Fans group and have for years now heard of the issue.  I offered a free repair attempt to a viewer because I wanted to see if I could ID and show an easy fix for everyone else to try.  The issue I found was a bad mounting of the ignition wire where it exists to the jets.  Scrape off the ceramic, disassemble the lighter, make sure the burner tubes are fully seated, trim the wires if needed to have a gap, reinstall and trim the wire end with a new bend.
