Hi,

The code can either be related to the fuel pump control module (FPCM) or the engine control module (ECM). What types of issues are you experiencing?

I ask because I'm trying to narrow things down. If you look below, you can see the different things the code is related to. Also, let me know if there are other codes or if this is the only one.

Let me know.

Joe
