You may not have one. If you have a Mass Air Flow sensor, very possible there is no map sensor.
I have a '92 LeSabre, and it does not have a map sensor, only the MAF sensor. I have seen a 2005 Buick Century that has both the MAF and a map sensor. On that one, the MAP sensor is on top of the intake manifold, on the passenger side of car.
SOURCE: repair manual
The repair manual is not available for free download. You can buy the Haynes book from one of the following sellers:
Auto Repair Manuals from Haynes
Buick Riviera Repair Manual
Buick Riviera Repair Manual - | 1995
SOURCE: fuel filter
the fuel filter is located on drivers side underneath the car about six inches past where the door shuts
SOURCE: Where is the fuse box on a 1990 Buick Riviera for
The fuse block is located under the center of the dash. On the left front
side of the console. I believe you're looking for fuse #2 20amp.
Hope this helps.
