Re: 4 cyl efi injectors wont spray need help

Hi
Not sure I understand your question properly. Injectors are normally grounded by the PCM, so with ignition on, you should have power to one of the 2 pins of each injector. During cranking, if you hook up a Noid Light, there should be a regular pulse at each one of them. No pulse means PCM is not grounding them BUT this doesn't mean the PCM is faulty, as there are a number of reason why it won't ground injectors, such as no signal from Crank position sensor, engine immobilized, an so on.
