ohm check the injectors. They should be around 12.6 ohms.

even though the computer in this car has an eprom, they are a programmable type, and you cannot swap it from your old to new ECM. You must purchase a new "blank" e-prom that matches the new ECM, then have that flashed to the car's VIN specs. That is where your problem is.
