So I just replaced my fuel pump as it died on me the other day. I did the cut a hole in the floor trick which in hind sight is a PIA if you dont cut that hole big enough. You will need to really wrangle that thing out of the tank and bend your lines a little. Good luck! I definitely broke stuff, but anyways got it back together. Truck started and seemed to run great. Started and let it run a bit, shut it down and after tinkering and buttoning everything back up I started it and soon noticed its idling high. I did mess around with my accordion air intake hose inspecting for cracks which it def has and put some more duct tape on it for good measure. Right after that I noticed the high idle. Checked to see if I damaged the accordion hose further or disconnected a vac line. All looks good.
If everything is normal and unchanged why is it idling high? Beyond that I dont think it idled high the immediately upon first start with the new pump. I think it increased rapidly at some point. It never had a high idle issue before, always settled back down after a couple minutes after cold start. Since it now has good fuel pressure from the pump is it possible the FUEL PRESSURE REGULATOR is bad now that it is seeing good fuel pressure and causing the high idle? Not positive, just freestyling here. I'm more of a monkey than a wrench. Thanks in advance.
