91 TPI fuel problem
We just put a new fuel pump in our 91 z28. Went to go start it with no luck. Found out it had no fuel pressure because of a bad regulator. After changing that out we have more then enough fuel pressure at the rails. It still wont fire. There is spark in every cyl fuel psi at the rails seems like its all good to go. The plugs are dry as a bone. No fuel smell nothing. Is it possible that all 8 injectors went bad? I cant figure out for the life of me whats going on.

you should get a "noid" light, it will test to make sure the injectors are getting the signal to fire from the ecu, they are also known as fuel injector test lights.
Hope this helps.
