Have the fuel pressure tested. Then clamp off the fuel return line from the regulator and test again. I'm guessing that the sensor you had replaced was on the exhaust. That would be the oxygen sensor. Try cleaning the MAF/MAP sensor. MAF sensor will be on the air intake horn tubing; MAP sensor will be on the intake manifold.
