For model year 1989 General Motors did not produce the Buick Park Avenue. The soonest production date to 1989 was the 1991 Park Avenue. The 1991 Park Avenue was offered in 3800 engine in supercharged or naturally aspirated. The part numbers for electronic control module (ECM) or "computer" will vary based on the exact engine for model year 1991s.
The crankshaft position sensor is mounted on the front of the engine. It bolts on, and has one wiring plug.
The Buick that was supercharged was called the Ultra. On the engine there is another unit mounted on top of the engine. It is driven by a separate belt from the drive shaft. The engine without the supercharger has only one serpentine belt.
No, it is an Ultra which means it is a supercharged 3.8L V6 and the 1995 Regal was a non-supercharged only so no. The supercharged models had an HD transmission and the Regal had the "regular verison". the transmission for the ultra was the 4t65e
