Default 1990 L99 C4 nightmare

Just picked up a 1990 it was starting at first but once you shut it down you would have to spray starter fluid after it cooled down to re start it this went on for about a week then you'd try again an it would start and stall so I was told may be the a fuel problem so I replaced the filter no go fuel pump nog the coil no coil in the distributor the anti theft bypass plug wires new injectors I'm not.getting injector pulse it will start with fuel. If you spray the throttle body but will stall. Once it's out it you continue to spray constant ly she will run stop it stalls I'm out of ideas please help

I picked up a clue from what you wrote. Did you say your not getting an injector pulse? If so, that would be the first thing you need to solve.

Google “1990 corvette no injector pulse” and see what you come up with
