I have just finished installing DW300 pumps and got those codes U0109 and U0128 , checked the fuse box in the trunk and they all seem well , I've also replaced the FSCM with no luck .

I'm not getting any signal from the fuel pressure sensor since it was pined to the FSCM , car runs great but wont start the secondary pump @ WOT , also is the parking brake has anything to do with this ?

Thanks .

There are some adjustments that need to be made.

I just did what I was told by another member and there was no issue.

Let me see if I can find the email. I'm not adept with HP like others so I was guided what to do.
