I've been having issues with my 2013 f150 5.0 lately. I'm having trouble starting the truck after fueling up. The last code I had pop up was P1450. I've replaced the purge and vent valve selenoid. I did have problem with fumes inside the cab but that seems to have gone anyway, however it does tend to smell strong outside usually just right after starting. I'm thinking/guessing maybe the charcoal canister needs replaced....possibly fuel pump..??? Idk. Any help or suggestions would be greatly appreciated. Truck has 175k BBK long tube headers/cold air intake/sct tuner
