issue is with 1987 420sel(my personal tank)

live in marfa, tx which of course is cold now...west texas

avg temp about 15F in marfa right now...when came out to start car this morning, all normal dash lights came on....buzzer for seat belt...etc

no crank....tried again nothing.....made sure car completely in park...no luck

finally after flagging someone down, i tried again and car started....could the cold be affecting the engine like a diesel? should i install a block heater?

shouldn't i hear click click click when i turn over the ignition?

after successful starting, drove 25 miles to work....just went out after 35 minutes and started car with no issues.....

ideas please.....
