N54 low fuel pressure issue new help

stephan47 · 05-16-2020, 10:22 AM

Alright so I'm still having some fuel troubles. For some reason I cant hit 70 psi on the lpfp during a pull. I have a new stage 3 fuel pump and yes both pump work independently and i just replaced the fuel pressure regulator as well as a new fuel pressure sensor im not getting any codes for it so at this point I'm at a loss at what to check next any ideas?. It is an n54 335

You. Better try LPFP sensor

This thing get me mad, change everything about the low pressure system to find out the issue was the sensor

How many are there ?
