What Could Cause Low Fuel Pressure besides a bad fuel pump or low voltage. I only have thirty pounds at idle and twenty pounds at fuel throttle.
Do you
have the same problem?

Maybe faulty pressure regulator. On fuel rail little silver can with hose. Remove hose pressure should rise. If not then pump faulty.
