    The Amityville Regal
    The Amityville Regal Dear Roy, I have a 1998 Buick Regal with a 3.8 supercharged engine that will start, but then dies. After a lot of testing, I found that the fuel pressure drops off immediately after starting.  I have replaced the fuel pump, pressure regulator and relay. The pump ground is good, and it has battery voltage while cranking, but I still have the same problem. What kind of demon is possessing this car?  Carl
