Wait, so the actual pressure is higher than the requested pressure, you said so.etching about the rail pressure being double... Sounds fishy?
Sounds increasingly like the ecu getting funky signals from the FRPS, is the FPR actually wide open, still just enough flow for the engine to run with, but the sensor saying the pressure is mental... IMHO check the voltage from the sensor, make sure it makes sense vs requested... Just because the ecu is receiving one value and spitting it out to PP, doesn't mean its correct, its another thing you can then discount....
hmm
