I have a 96 chevy s10 with a 4.3 v6 that wont start its getting fire fuel pressure isn't were it needs to be when the switch is on but when u put gas in the throttle body it starts no problem.

It could be just a clogged or dirt in the fuel line.. Before you go into expensive parts, add a bottle of 'Fuel Injector Cleaner' to the gas tank. This is what worked for me! Let me know if it works for you. Good Luck! De Bo ;-}

Also, check and replace your fuel filter !!
