So my fuel pump has been sounding louder than normal at cycling the key and you can here it running when the truck is at idle. When i step on it first and second gear shift fine and then it falls on its face. I will have smoke at first and then i lose the fuel i guess and then it is starving for fuel. I think i got some $hity fuel and i believe i got some crud in the fuel pump... How do i go about cleaning the pump out? I got a tech that is going to drive it and see what he thinks but i though i would pick your guys brain first! Any help???
