1975 Jeep CJ5 • 50,000 miles

I have a '75 Jeep CJ5 Renegade. It still has the original Prestolite ignition system. I am trying to make sure all of the wiring is working properly so I can install a more reliable ignition system. I want to put in the 1979 Jeep CJ7 distributor, a GM HEI module, a Ford TFI coil and etc. I have been having problems getting it started. I have done all of the basic troubleshooting tests to see if I can figure out the starting issue. I tested to see if I had battery voltage to the "S" terminal of the starter relay when the key was in the "start" position. The test showed I did have battery voltage to that terminal. However, I did not show battery voltage at the "S" terminal while in the "Run" position. I also checked to see if I had 12 volts at the Prestolite ignition module and the (+) terminal on the ignition coil. I did have good power to those two items. I did the test where you disconnect the green wire to the (-) side of the coil and I got "flashing" while the key is in the "start" position. The vehicle will start but it will not stay running for more than 3-5 seconds. I am thinking that maybe I have a problem with the key ignition switch that is located on the dash. This particular year of Jeep has a single light blue wire that comes directly from the ignition switch and is "hot" in both the "run" and "start" positions. Do you have any tips I could use to help me narrow down what the problem can be? Thanks!
