The most obvious thing to check when a 1991 Oldsmobile Cutlass
Supreme won't start is to make sure that the vehicle has gas. You
should also check the battery. If the car clicks when you try to
start it, it is likely the alternator.
The headlights go up and down when you turn the headlights on.
If they are not going up or down they may be disconnected from the
motor. You would have to take the headlights out to see if they are
disconnected or not.
