ok my check engine light came on so i went to advance and got it scaned. the code they pulled was p1641 fc relay 1 contol circuit mil requsted. i also noticed that my fuel pressure is on 65 instead of 38.is the fuel pressure related to the code and if so how do i fix it? thanks joe

 

P1641 is a Fan 1 Relay Control code. I doubt it's related to your fuel pressure.

 

I already answered this identical post on another forum. Generally not a good idea to post the same question on multiple forums. Post it once, on the correct forum.
