All, I’ve not found any answers on this topic for my2003 mustang gt! Still getting P0190 code after replacing:
Fuel pump
Fuel filter
EGR valve
plugs
fuel Rail pressure sensor
FPDM

FRPS connector and wires look fine. When code comes up car is hard to start. I can reset and it comes back up after a few times of starting the car, any help would be appreciated!!

The FRPS is a "no start" sensor. That is IF the PCM is not receiving a valid fuel pressure signal this will create a crank with no start symptom.

Do you have an ODB2 sensor? If you did it might make short work of this problem. If this were my car I would monitor the FRPS while performing a "wiggle" test up and down the harness. Look for a change while monitoring the FRPS.

ForScan ODB2 scanner w ELM327 USB

Just wondering. Did you change all those parts trying to resolve this problem?
