I have a 04 and the other day the fill (lift) pump left me stranded on the side of the road. I replaced the pump and filter started the truck and all was fine. To day I got my scan tool out and cleared the code, The problem is that the code will not clear, scan tool tells me it successfully erased the code but if I run a second scan it is still there and the check engine light is still on. Any body have thoughts on my isue?
