Somewhere along the lines of me installing my new Hydra tuner, I took the PCM out of the truck while it still had power going to the PCM (ignition issue). Now the truck will spin, but will not fire. No wait to start light, RPM's ARE jumping up when its spinning, but no start. Odometer reading the correct miles, ABS light coming on. I can plug the chip from the Hydra into the PCM, and the tuner power's up when turning the key, but will not start. I have checked all the fuses, all of the relay's, checked the connection on the PCM, making sure the bolt is tight where it goes into the PCM. I have taken the PCM back out, and taken it apart again, and cannot see anything on the PCM visually that would be any reason for this. I would usually say it is the CPS, but the RPM's are jumping when it is spinning over. NEED HELP!!
