Question about 1989 Chevrolet Caprice
The injectors on a TBI are going to spray gas only when the engine cranks over not when the key is turned on. With that said you may have a bad pressure regulator in the TBI. The rubber in it may have a hole in it not allowing it to build pressure for the injectors. However, before doing that I would check to be sure I had power to the injectors. You can purchase a noid light at the parts store and check to ensure you have power to the injectors in the TBI they are not that much.
