The pcm is picking up an injector or wiring fault. With the key ON, make sure there is power to the pink wire that goes to each injector. The other wire receives a ground from the pcm to fire the injector. That can be checked with a "noid" light. Injectors can be tested with a meter to verify the resistance is ~12 ohms.
