So I switched the tune and loaded both my tune from full blown and my stock tune and with both of them I had no maf sensor code.
As for my fuel pressure I have 2 high pressure pumps and a known good DI module. Low side fuel pressure is getting there confirmed with mechanical gauge but it doesn’t seem to be creating pressure. I disconnected the connector for the high pressure pump and checked with noid light to make sure it was receiving the signal and it is receiving it.
This is a issue that I had at times before the built engine too just now on a completely larger scale. My fuel presussure on high side would randomly just drop. Normally I would turn the car off and let it cool down a bit and it came right back.
I was thinking the fuel pressure sensor maybe? But again wouldn’t that throw a code? I bench tested as per service manual but from experience it doesn’t always mean it’s good even if you bench test it.
Still fighting this issue please any help is appreciated!!!
