Message	I've had more than 3 ECU's with bad injector circuits in the past 6 months.. Try this use an LED .. unplug number 4 insert the LED .. Also remove fuel pump fuse first.. having someone turning the key and watch the LED.. it should flash on and off.. Since the LED is directional. You may have to reverse it .. If it still does not flash on and of when the engine is turned over.. It could be the ECU or the CAS.. If using a known good CAS and it still doesn't flash ,, you may need a new ECU..
