2014 camaro

I've installed a Deatschwerks fuel pump in a 2014 Camaro and basically a standalone fuel system. i used the grey factory positive trigger wire for the pump relays. i cant get the check engine light off now. I've went in and turned the drop down to no mil I've changed it to no error reported, checked and unchecked the SES Enable...is there something I'm missing?? Thank you for any help!

Probably the FPCM triggering the faults, which is separate from the ECM fuel controls. That would be my guess.

i think maybe its the U0109 code. Looking further this code was still set to trigger MIL. Loss of communication with fuel pump?

Not sure, but the ECM sends a fuel pressure request to the FPCM, so the FPCM is what actually controls the fuel pump. Id look into turning off faults for the FPCM.
