What’s the charge on the battery at? How are the connections at the battery posts and at the starter/chassis ground?

Check the positive battery terminal for corrosion.

If it’s heavily corroded, replace the cable assembly.

If I had a car with a side post battery I would keep a 5/16/8mm wrench in the glove box.

My Corolla had a no-crank out of the blue. It happened when I tried to start the engine after I had stopped for gasoline during a rain storm. I noticed during attempted cranking all the dash lights would dim. I checked the battery connections, and the positive was a little loose. Twisting it slightly restored cranking.
