no start/hard start

[99stackedpowerstroke]

so the other day i drove my truck to work and no problems, i went to leave work and it cranked alittle longer than usual but fired up, now it wont start, fuel bowl is full of fuel and after the bowl builds pressure it sounds like its sucking air but not leaking fuel, and it stops sucking air after the pump stops pumping, its not getting fuel, i know this because im not getting smoke out of exhaust,
