I just realized this link is from two different people. I only saw the last one. As you are aware, it will have either a carburetor or fuel injection. I suspect when you say carburetor you are referring to the throttle body.
I attached an exploded view of the throttle body with injectors. Please confirm that this is what you have.
Next, the throttle body injectors (TBI) are controlled by the engine control module (ECM). We may have a wiring issue, a failing ECM, or even a failed fuse.
Pic 1 below is an exploded view of the TBI and the remaining pics are the diagnostics for the injectors. Take a look through them and let me know if you have questions.
See pics below.
