It will start but will not idle or run

(1990 Ford Aerostar)
in Quinlan, TX on March 09, 2011
Ok here what I have done so far. I have changed the fuel pump and fuel filter. Changed plug and wires. Fuel pressure regulator has also been changed. The only way I can get it actually run is spraying carb spray into the intake. I have checked for vacuum leaks but not that would keep it from running.

You need to check the fuel injectors for power and ground control signal, the injectors should be hot when the EFC relay is energized (when the ignition is on), and the ground is controlled by the computer. Look for connector problems between the injectors and the computer. Make sure you have fuel pressure when the engine is cranking.

I figure it was a bad relay however changed them and nothing changed. I am pretty much going to have to change out the computer brain. I just refuse to believe that all 6 of the injectors are stopped up or not workin
