Does anyone know whether the fuel pressure or fuel rail pressure is accessible using OBD2 please? I have a simple cheap OBD2 reader that when disconnected shows slots for both of these items but when connected to the car the options disappear. I am trying to monitor pressure decay after shut down to check for leaky injectors. Many thanks for any help.
