Whats the other ones? The other are probably the one causing problems.

I think I figured out the problem. The shop let my batteries die and now I'm having issues. Truck won't even start bc batteries does in between changing tunes just now. Hopefully this will fix it when I go get new ones

Didn't the shop test drive there work? Good luck.

New batteries no fix it. Seems I'm not much fuel through the LPFP. It will not drain anything when I open it up.

Factory?

Yes. Until my fass is installed

Have you drained it recently? Could be plugged up what I'm getting at I guess. Correct me if I'm wrong but I thought you could get an psi idea via fuel cooler Schrader valve? Codes?
