fill out some info on your truck in your signature...how many miles?
you might have had your fuel drain back. many of these trucks will develop a minor air leak in the return and the fuel will empty into the tank. since you probably have a mechanical fuel pump you then need to crank the truck till it is full of fuel again.
you can try cranking the truck then open the valve on the fuel filter housing and see if it squirts fuel or just air. it should squirt a little fuel out, if not then thats probably your problem.
Your idle problem could have to do with your injection pump timing being off. has anyone messed with your IP? it may be off a little. you can adjust it by loosening the nuts that hold it on and rotate it slightly and see if it settles the idling issue.
