yep, so battery was indeed shot and come to find out i also had the wrong battery in the truck. so now ive got a new one and the correct battery. still no start. its turning real good but not starting. my uncle seems to think my fuel pump/filter is clogged and i think its the alt because my GEN light is on the dash and that has to do with the charging system. says it in the owners manual. problem is i dont wanna replace parts that dont need replaced. any ideas now that the battery is not a question?

Turn the key to on. Does the fuel pump run? If it does, get a pressure gauge, and test it. Should be right about 49 psi.
Are you getting spark?
Do you have power at the injectors? (if the engine ain't running, you only get power at the coil, and the injectors, for about three seoncds, or until the PCM sees the engine turning.)

Gen light generally means charging system fault when the truck is running. Not starting now sounds like the fuel pump went out. When you first turn the key on can you hear the pump cycle (a helper can be handy here)? If not you can try hitting the bottom of the tank (not hard enough to break things) to shock the pump into working. This doesn't work very often, but can. As with the alternator, hitting it is only a "get you home" fix.

i was told to turn the key and listen for a "click" sound. i couldnt really hear anything. i have no idea about the injectors or how to check that. also im pretty sure im getting spark. why would the gen light be on if i cant even get it started. the first time i saw this light was when i couldnt get it to start. i searched GEN light and all i could find is alternator is bad. i hope its the alt and not the fuel pump. how hard is a fuel pump swap? dropping the tank un bolt a couple things and good to go type of thing?
