Fuel system will not hold prime
I replaced the fuel pump a few months ago because of a leak in that area, thought that was it. With diesel high the truck sits all week until I use it on the weekends. Wehn sitting all week, it takes awhile to get it running. It seems the fuel is draining back into the tank each time because when first turning over hte engine theres no smoke and combustion. As I keep trying you can see it building up then takes off, but will almost kill my battery doing so.. Its pretty warm here so I am sure its not cold. I also replaced all the rubber fuel line between the pump and the filter. Could it be the pump?
