not sure where to go from there without seeing it , id start cheap and replace the fuel filter after its set for about a day without the key being moved or touched , maybe before that go thru and check all the fuses might just be a old fuel pump fuse that blew out
might have someone spray some cold start starting fluid in the airbox while you try to start it , if it tries to run then it might be worth looking into the fuel system , if it doesnt chage anything id venture towards the spark side of things
some of the trucks i used to work on had a weak starter which didnt turn the engine over fast enough for it to fire off , but these were diesls
like i say hard to tell without looking at her , so it quit running after it set for a night? was it after you put gas in it ? sometimes people get water or other stuff after filling a car up
