What was Gomer Pyle's occupation before becoming a U.S. Marine?

Before becoming a U.S. Marine, Gomer Pyle worked as an auto mechanic. On The Andy Griffith Show, he is introduced as a gentle, naive mechanic associated with Wally’s Filling Station in Mayberry.

Gomer’s mechanical abilities are part of the character’s comedy. Early episodes portray him as inexperienced and sometimes confused about automotive parts, yet he gradually proves capable of diagnosing and repairing vehicles. His job also gives him a natural connection to the town’s motorists and creates situations in which his optimism clashes with practical problems.

Jim Nabors played Gomer, who first appeared during the third season of The Andy Griffith Show. The character became popular enough to receive the spin-off Gomer Pyle, U.S.M.C., which premiered in 1964. In that series, Gomer leaves civilian work and joins the United States Marine Corps, where his innocence and enthusiasm frustrate—and eventually win over—his stern drill instructor, Sergeant Vince Carter.

The answer is sometimes confused with Goober Pyle’s occupation. Goober, Gomer’s cousin, is also an auto mechanic, and both characters work around filling stations. Their shared trade is one reason the two Pyles can be easy to mix up.
