Check the grounds, make sure the all your engine harness plugs recheck them. U1000 is no can communication.... My car was bad IPDM and bad ECM same code.. If your car was working before repair then something not plugged in.. or ground or blown fuse. Get yourself a FSM for your Z you can get them at the top... FSM and finding CONSULT3 on the internet helped me repair my Z.
