Check compression, if it has sat too long and has a lot of miles on it the possibility of collapsed rings come to mind, if compression is low then squirt in a little oil into each cylinder and see if it will fire then.

If you are getting fuel and fire check for a clogged catalytic converter.

even when my truck was getting fuel and fire it still wouldnt start cause the fuel pump wouldnt put out enough fuel so it could be your fuel pump.
