1995 Regal, 3.8L, 130k miles. Lately, the vehicle would surge like it is
starved for fuel, also is difficult to start at times. Replaced fuel
filter, fuel pump relay, pressure regulator. Prior to replacing the
regulator, I would hear the fuel pump turn on and the vehicle ran fine.
Then starting problem developed, so I changed the regulator (thought that I
smelled gas in the vacuum line.) With a pressure gauge connected to the
rail, I see 18-20 psi with the vehicle at idle. I still do not hear the
fuel pump run when the key is turned to on. With the relay removed and 12V
applied directly to the pump, I get 20 psi at the fuel rail with the vehicle
running (still do not hear the pump.) Is the pump running slow....that is
why I do hear it? Could the strainer in the tank be clogged, that is why
the low fuel pressure? I didn't think the vehicle would start with the high
pressure pump being inoperative. Could the pump be gummed up and running
slow? Is there a low and high pressure pump in the tank? Any help would be
greatly appreciated. Joe

From what info I can find fuel pressure should be 28-32 psi at lde. Looks
like it's time for a pump. There is only one fuel pump and it is in the
tank.

Yep, its time for a pump.
They wear out.
