What is FPCM??
I looked in a 2011 file I have and can't figure out what you are asking.
fuel pressure control module... i guess i should have dug a little before posting i found it. the trouble im having is i installed a stainless return line but left the fuel pressure sensor on the stock line and the pressure sensor isnt seeing any pressure so it signals the fpcm to basically flood my engine and it wont start
Disabling the FPCM from the file will it work?
It's fairly simple. Run a new 12 or 10 gauge power wire to your pump off a relay. From there you can yank the fuse out of the FPCM and delete the lost communication code. Enjoy.
If I just run the wire off to a relay and not yank the fuse and not erase the code will it still work?
Or it will give problems?
I'm about to instal a 450 in tank fuel pump wot bigger gauge wire to my truck.
the problem is something in the SD tune put the MAF tune back on and no problem at all. walbro 450 seems to be fine with the FPCM
