98 LeSabre won't start

My brother has a 1998 LeSabre with the V6 3.8 automatic..He parked it last week and now it won't start..The engine cranks fine but it won't turn over..I pulled off the plug wires one at a time and all 6 cylinders have plenty of spark..Plugs look fine..I smell gas but otherwise am not sure how to tell if the engine is getting gas..There are no blown fuses...Any input is appreciated :)

Welcome to AF, see if it starts by spraying a small amt of starting fluid into the intake.
