JEEP CJ7 ENGINE PROBLEM

1979 Jeep CJ7 • 100,000 miles

79 Jeep CJ7 wont start.
i was om here before with my CJ with a wont start issue. That turned out to be a bad coil, started fine after. This weekend I changed out my turn signal switch and now I cant get it to start. I think I put everything back where it should be, maybe I missed something. I tested the run possition power and starting position for the key while starting and I get 6.5 volts at run, and 12+ volts while starting at the coil. So I think my module and ignition swith are ok. This was all working untill I changed out the turn signal switch. What am I missing or what did I not do right?

THEN PULL #1's PLUG WIRE OFF----SHOVE A NAIL, PAPERCLIP, ETC INSIDE THE RUBBER BOOT, IN BETWEEN THE CONTACT AND THE RUBBER

HOLD THE PLUG WIRE W/ NAIL (THE NAIL) ABOUT A 1/4 INCH OR LESS (HOVER) FROM SHINY METAL ON THE ENGINE OR A BRACKET (DOING THIS IN A SHADED AREA WORKS BEST!). HAVE YOUR BUDDY TURN THE ENGINE OVER WITH THE KEY. ARE WE GETTING A STRONG BLUE "POPPING" SPARK FROM THE NAIL TO THE BRACKET?
