right, but im not sure why thats acting up after replacing the pump. the reason i brought up the pump was b/c of the gas guage fluctuating. i need to make sure its securely seated in the clamp to try to get rid of the needle dancing  so is the assumption here that replacing that sensor/regulator will fix this or is this a fix that could still not be the fix? (tricky question w/no correct answer)
P0190 - Fuel Rail Pressure Sensor Circuit Malfunction
The (CCM) monitors the FRP sensor to the PCM for VREF voltage. The test fails when the VREF voltage from the PCM drops to a voltage less than a minimum calibrated value.
* VREF open in harness or sensor.
Looks like a bad connection in the harness from the PCM.
Check all wiring that goes to the fuel pump assembly. That explains the gas gage too.
