Answers :

COULD BE THE FUEL RAIL PRESSURE SENSOR OR YOU HAVE THE WRONG FUEL PUMP FOR THE VECHICLE.PCM COULD BE OUT OF CALIBRATION.TURN OFF RADIO FIRST THEN DISCONNECT NEGATIVE BATTERY CABLE FOR A MINUTE THEN HOOK BACK UP NEGATIVE BATTERY CABLE.THEN CRANK CAR UP LET IT GET OPERATING TEMP BEFORE THROTTLING IT.GIVE PCM TIME TO RECOGNIZE THE NEW FUEL PUMP.
