Ignition module. See if spark plug wires have arched. Check for spark. You could change it yourself. Module plus new wires will cost you around $200.

One reason a 1993 Chevy Lumina may turn over but not start could be the battery. It may also be the spark plugs.

Correct gap is .045 for the 3.1 engine.

A 1997 Chevy Lumina with a 3.1 that will not start, turns over, and doesn't spark; most likely has a defective ignition system. The coil may be damaged or wire providing power could be damaged.

The engine can be moved forward slightly.

Get a shop manual. There is no distributor. These have coil packs.
