alright!
Figured it out!
i'm dumb! haha!
basically what happend, the day all of this started showing up, i had ALSO installed my twin kennedy lift pumps. To do that, i drained my fuel lines, and never re primed anything. so, the reason the truck wouldn't start was: i was sucking air!
thank god!
now that i have that hunted down, i'm good to keep rollin'!
thanks for the suggestions and help you guys!
