SOURCE: How to replace ECM in 1995 Buick Riviera. Do I

Yes, disconnect the battery first, Then be sure you do not have a staitc charge on your clothing when removing and installing the new ECM. A static shock that jumps from you to the unit will cause it to burn out.
Hope this helps.

Where can I find the map sensor on a 1990 Buick Riviera 3800

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.

My 1990 riviera will run great, as you are going down the road it will shut off,but crank right backup. whats wrong?

Check the ECM part number. If it is a 1228253 that is your problem. get a 16198264 the other number does just what your car is doing. I worked at a Buick dealer and know about the problematic 1228253 ecm.
