Fuel pump went out, replaced it yesterday, but it's idling low and acting as if wanting to stall... Replaced with OEM AC Delco for flexfuel... any suggestions? :roll:

Did you do the filter at the same time? Is your truck a flex fuel vehicle? Check the fuel pressure regulator on the side of the fuel rail.Remove the vacuum line and see if there is raw fuel in it, if so replace regulator
