Last shop that worked on it said I’d be getting different codes if it was the fuel PCM going bad. Only thing that looks strange to me on live data is the fuel rail pressure sensor voltage. Is always hovering around 0.0097volts vs the low pressure sensor voltage is around 3.57. If I unplug the HP sensor the car runs rough and reads 0 volts. But it clearly works, at door open after a day or 2 of sitting. Rail pressure is 105psi. Fires right up immediately no hesitation and high idle is 2170 then running idle is between 1034 and 600 depending on what is on( a/c, air suspension compressor and so on)
I messaged GAP and sent them the codes and info. I was told it is NOT an ECU problem, check wiring. But if it were a wiring issues would I be seeing sporadic readings? I’m trying to find someone nearby that has an L405 I can compare data to but that’s proven to be a dead end.
