Default no idle

my truck wont idle, if i play with the pedal enough and slowly let it down and keep my foot on the pedal a little bit i can get it to run at 800 rpms but if i take my foot off the petal it just falls on its face. it can idle at 1200 rpms if i bump it up enough. just changed the fuel filter, no affect... on accident i ran it pretty low last night which is when it first started to happen.. prob only had 5 gallons left in the tank... pushed the primer button a 100 times at least... could it be the lift pump? i have no idea what to do now
