hey everyone, got my good ol trusty 91 formula firebird 305 tuneport. it wont start on its own, in other words i have to spray gas in the throttle itl start then stall when the gas fumes run out. i know my problem is my injectors wont pulse the fuel in. my fuel pump is good, my filter is new. i dont think the injectors are getting the electronic signal. it ran fine yesterday i installed an new coolant temps sensor an started it up, shut it down went to go start it an i just cranks. as i said i did a little diag so far but i need help on what could cause the injectors not to work. my VATS is in working order so its not that im just a little clueless and very frustrated

 

do you hear the pump priming before you try to start?
