I checked the timing, checked all the terminals at the ignition switch with key in run and off position, I have a full msd ignition system on it so it's not anything like a ballast resistor or anything. I'm thinking maybe starter relay? Anyone have any thoughts? Thanks for any help

The starter relay should not have any effect on the ignition functioning once you let off the key and it returns to the "run" position. I would imagine that you have a problem with with either the ignition switch, bulkhead connector, or the splice where the "start" and "run" circuits meet.
