Default 84 vette will start with starting fluid

My vet starts and stays on but to start it I have to use starting fluid. I replaced the fuel pump, fuel filter, fuel pressure regulator, fuel relay switch,and key cylinder . Can any one help??

Is the throttle position sensor voltage set correctly? Is the temperature sensor in the front of the intake manifold working properly (this one tells the computer the engine temperature and so sets starting mixture)? If it is original... its over 30 years old!

When you're cranking the starter, are the injectors spraying fuel? I'd guess no, since it doesn't start (but starts on ether) but that would be step 1.

If no spray, step 2 would be checking fuel pressure.
