do these trucks have a screen in fuel tank? if there is alot of debris / rust in tank, it can plug screen. after sitting awhile the sediment falls away from screen allowing fuel to pass until screen plugs again. when the truck wont start, pull the outlet line off fuel pump and crank engine. if fuel pumps out while cranking the pump and tank are ok. if no fuel, remove inlet line from pump have some crank engine, hold your finger over inlet port on pump. you should be able to feel suction. if no suction, replace pump
