What kind of scanner do you have? if it is capable of datalogging, or watching live data, look for fuel pump duty cycle, or fuel pressure, or fuel pressure at the rail, and make sure its at least 30-35. if that number dips significantly while driving or accellerating, the fuel pump, sender, or other fuel pump related device is malfunctioning.
If the duty cycle is the setting your watching, it would jump very high while accellerating if theres a problem.
if your reader cannot show this data then,
get a pressure gauge, and test the fuel pressure under the hood. schrader valve, passenger side of the intake manifold i believe.
