If you have continuity from the DLC back to the PCM on all the pins that it should, and the PCM has power and ground everywhere it is supposed to, you probably need a PCM. Before I throw a PCM at it though, I would make extra sure that you have checked all of the stuff that I spoke of first. Remeber the PCM will have more than one power and more than one ground input.
