Verify the wires are good. If they are, bad PCM. Pay attention to the connectors as well, sometimes they expand a bit, and don't make good contact.

Very little to no resistance. You can download the service manual for your truck from here. Wiring diagrams are in section 8W. There will also be a connector pinout section as well. Need to test all four wires.
