1984 Ram Crank No Start

between the distributor impeller and the pickup, think it's supposed to be like .008 ths. of a gap
I'll check tomorrow.
Ran fine, then nothing, that gap 'shouldn't' have changed, stuff happens.

Years ago I had a bad pickup, it was cracked, only when hot it wouldn't start.
Start cold, run hot fine, turn it off no start.
Let it cool, start fine.
Opposite of current issue, but got to check everything sometimes.
