You may have a bad PCM. The injector drivers in the PCM could be shorted out. If you have a test light, connect one end to 12v and then touch the lead in the injector connector to see if it lights up. The lead you should test is the one that is not pink. Turn the ignition switch on with the fuel pump power lead disconnected and then probe the fuel injector leads. None of the leads should show ground by illuminating the test light. If this test shows no grounds, your injectors could just be stuck open.
