Dashes in the IPC indicates that the PCM and IPC are not communicating. Based on his symptoms, I suspect a network issue. He will need ForScan at minimum to determine which networks/modules are affected.New battery and check the starter relay (#3 I think, under hood) just in case? I had that one out once and tried to start it (really don't think that's your problem because the dashes on the odometer, that's gotta be PCM or BCM, but anyway) and it throws a "Start system fault" message on the Instrument Cluster. You don't see anything come up on the IC?
