Yes I did try reforming the capacitor's in the vivitar, no luck. The new flash came in, and same problem no sync. So I decided to break it down and check all the connections and clean them. In the process I found a green wire (looks like ground) under the bottom plate where the batteries are installed, it was lose. So I soldered it back into place, reasembled and viola it all works great now. Problem solved, thank you to everyone that posted you all have been a big help.
