1989 Chevy Blazer 6 cyl Four Wheel Drive Automatic

I have a 1989 Chevy Blazer, we have replaced the fuel pump, fuel filter, the ignition control module, the fuel pressure regulator, the idle air control valve. The fuel injectors are spraying gas.
The engine will not start unless primed with starting fluid, and it stalls out going down the road and at stop lights randomly, then will not start immediately after. This happens whether full tank of gas or at a quarter of a tank. I have to keep my foot on the gas and the brake simutaneously to keep it running for the most part.
Ran a diagnostic on it and there were no codes showing. Any ideas where to go from here?

Do you hear the fuel pump come On when key at run-if not check the fuel pump fuse, fuel pump relay and computer fuel pump control circuit.

Replaced old fuel pump with electric fuel pump. You can hear it kick on and prime. Started it up this A.M. Drove it a quarter of a mile and it died, tried restarting but would not, finally shot it with starting fluid and crank it over, drove back home; turned it off, then tried to crank it again, refused to start. Will try to crank it in a couple of hours.

Check the fuel pressure with a fuel pressure gauge-
