SOURCE: Fuel Pressure Regulator
All Fuel Pressure Regulators are usually attached to the Fuel Rail. In any case, they have a return line to the fuel tank. On your engine you may have to remove the pretty "Plastic Cover" that covers the top of the engine to see the fuel rail and the pressure regulator. Look for a "tube" that has fuel injectors going from the bottom of it and into the top of the intake manifold. The fuel pressure regulator is a round looking device attached to the end of the fuel rail with a small fuel line coming out the botttom and a vacuum line attached to the top of it. At least in most cases this is what it will look like.

How do you know that it is the regulator?
these 4.3 motors had a lot of trouble from 93 to 98, I know I had 2 of them.
What happened to mine was that the intake kept getting very carboned up. After I would clean it, the truck would run fine for about 5 or 6 months, then same thing.
Theres actually a class action lawsuit about this that I believe has been settled, you may have recourse if you bought it through a dealer. Good luck.You'll need it.
SOURCE: I need to replace the fuel filter, 1994 Buick Century Custom 3.1
Find fuel lines, there should be a threaded port on the intake line. Push in with a drill bit, key, or some kind of thin metal to release pressure. Basically gas will just spray out. When I worked in the shop, I never released pressure, I just unhooked a line near the tank and let it drain for 15 seconds. To prime, turn the key into run position leave it there for 5 second, then switch it off again. Do that 4 or 6 times and it should almost fire right away again.
SOURCE: I have a 1987 Buick Century. That stalls out
I'm not Roger but can tell you this....if you have a bad crankshaft position sensor or a corrupt ECM....your car will do that.....last things could be the timing belt.
SOURCE: where is the fuel pressure regulator located in my 1994 safari 4.3 liter
