i recently put a fass 150 fuel sytem an electric fans on the truck an a smarty. now that i have the smarty i have codes that keep coming up its a low voltage at the lift pump and cooling fan 1 speed an cooling fan 1 curcut code is there any way i can get them to stop showing up? also when they are present i dont get an engine light i get dining an the preheat light comes on an stays on. any help would be great

The fan ones will always be there since the fan clutch isnt plugged in, i have them on my truck also. I dont get the grid light or a dining so it must be from your Fass system. How did you wire the Fass system in?

we had t into another wire for power cause the truck didnt have the in tank pump. wired just how they said on the fass website. i wanna say it was something like an m11 harness i cant remember:s:
|
What is the code number for the lift pump code.
|
p0628

Sounds like the computer is mad that the factory lift pump is not running, id ask the vendor you got the system from if you can jump a wire on the factory harness to make the computer think the pump is running.
