What can a bad fuel pressure regulator do to a car? What are the symptoms?Weegy:
Low pressure will make the car stall, or run like it isn't getting any gas.... jerk, cough...
High pressuer will make the car run rich, to much gas, and could stall, flood, and be hard to start.
Most cars have fuel pressure regulators that keep the fuel at the proper pressure, but if it is low, then the regulator can't increase the pressure, not much. In that case, the filter might be plugging up, or the fuel pump is going bad.
But the regulator could also go bad, and not keep the presssure regulated.Auto Answered|Score 1Weegy:
