my truck just started this 2 wks ago. it stalls randomly. it will not pump fuel to the thrtl body when cranking. if i can get a good push, i can jump start it. (5speed). or, if someone is cranking while i'm spraying tons of either and, it will eventually start. i've replace the fuel filter and the relay. help me!! i dont have a lot of time as i use my truck for work. i'm a tech, and have to drive all day. and actually, other days it's fine. regardless, it does start every mornig. see my confusion?
