Trouble starting up 67 GTS Dart After winter storage.

Check the reluctor gap.

If one of the bushings is worn in the distributor body the reluctor gap will be out of tolerance.

This happen to me on my Mopar Performance distributor and to another guy I know with the same distributor.

In both cases the engine started to run rough then quit and wouldn't start.

For some reason those bushing in the Mopar Performance distributors wear quickly.
