Potential stuck injectors.
Potential wiring problem--no power to the injectors. Power is (should be) supplied by a fuse and harness whenever the key is in "Run" or "Crank".
Potential wiring problem--Ground side of injectors, all the way back to the computer. Computer grounds injectors to fire them.
Possible but unlikely--failed computer.
Engine runs with fuel supplied--ignition system likely OK, as are compression, rings, valves, cam timing, etc. At least good enough to run at idle.
Verify that the injectors have power with key on. I'd run the engine with external fuel, and tap on the injector housings with a tiny hammer or other implement to see if the shock will free the moving parts inside. Perhaps connect a noid light to the injector harness to see if it blinks, indicating both power and ground.
