i have 1996 gmc 5.7 vortec has spark, changed fuel pump has power to fuel pump.i poured gas in tbi will not fire ?pl help

First of all don't pour any more gas into the throttle body it's not a carburetor that engine is fuel injected you'll burn up the intake if it ignites! Check the spark like and check the pressure in the fuel rail also open the gas door and listen for the fuel pump it'll make a zooming noise if its working keeping in mind the control module could be bad my truck did the same thing

could be a clogged air ( air fuel spark if all three arnt right she wont fire )
