P0174 and P0171 codes
I keep getting these codes on my LS swap. Its an LQ9 stock other than headers and a cold air intake that I fabbed myself. I'm using the PSI conversions computer and harness. I put a fuel pump in the stock tank, and it's getting 45 psi at the fuel rail. But- it was a cheap pump off of Amazon and I have suspicions that it is the culprit of my codes. The engine has 3/8 supply and return lines.
Do I replace the pump or look to having it tuned?
