no start new injectors on 1992 Cadillac Eldorado

I have a problem with keeping the car started. I just replaced the fuel injectors and a complete tune-up has been done all in the last week and the car will start but will nto stay running. The rpms jump all over the place prior to cutting off and as long as I spray starting fluid into the carburetor it will continue to run. Can anyone help with what else may be wrong with the car not staying started?

Check your fuel pressure, you may have a failing fuel pump.
