SOURCE: 1998 Seville SLS, 42,000 mi, Limit speed to 90mph.

it mean that one of the electronic load leveling sensor is not reading. that sensor tells the air pump to fill up that air shock or air bag. the sensors maybe reasonable price wise but if the sensor is reading that an air shock is not holding air pressure and an air shock is not cheap.

SOURCE: What kind of brakes are on my 1998 Cadillac

Both, actually. In the front, disks.
In the rear the main braking is a similar disk, and much smaller is a drum, essentially in the hub area of the disk rotor. In there are cute little drum breaks that are the emergency or parking brake. Do inspect and adjust them, while you are in there.
Familiarize the feel and effectiveness of the parking brake before you start...so you will know.

1999 seville sls gas lid will not open

Check your fuses. If you can't find a bad fuse, it could be a faulty solenoid that opens the door.

There should be a manual release in the trunk near the gas door.

Where is the oil pump?

Probably not. Make sure you have a clean oil filter and check the oil level. Also, make sure the oil filler cap is secured.
