I have a 72 Z that I bought new from PaceSetter in Rochester. It has 242,000 on it. About a year ago I overheated it and it started blowing blue smoke. I figured I had melted the valve seals so over some time I got a rebuilt head and replaced it. Got it funning and it still blew smoke so I figured it need the bottom looked after. had arranged to take it to a place for the rebuild but now I can't get it started. Everything seems to be normal up to the started motor starting. So, I have: Charged/checked the battery OK I have taken the started motor to Kragens for testing OK I have replaced the starter switch (not the key part) OK I have replaced the coil OK I have changed the ballast resistor I have checked the starter relay. So, when I try to start it, when I turn the key in the Acc. position all is ON and the radio comes one. When I turn to ON, the starter relay clicks. When I turn to start the relay clicks again but nothing happens. It is an automatic so I have also tested that switch too OK. The coil wire to the distributor is intact. I am at a loss. Any ideas would be appreciated.
