I'm still confused, is it a TBI (Throttle Body Injection) or a carb?
A carb does not have "injectors", but if it is a Holley it does have 'squirters' (otherwise known as Accelerator Pump Discharge Nozzles). nuff said.
If, in fact, it is a carb, then the accelerator pump is not working.
If it is a TBI, then I have no help for you. I have never worked on fuel injection before.
