    Hello ilunn the master is the engine ECU .all others are connected via can high and low signal wires .is that car automatic? Because one of the communication errors was to do with the transmission on the last picture he put up .

    No manual transmission, did try CAN resistance at engine ecu but got know resistance value! looking at circuit diagram it does not show any resistors unless there built in to ecu but then again expected to see 120 ohm or 60 ohm but no just got 0.

    There are 2 resistors , 1 is built into the ECU I think the other is in the dashboard binnacle.
    Both are 60 ohms ,so equates to 120 ohms , you should be getting 60 ohms , no matter where you test from .
    If no resistance then as you know there's a lot of current flow going somewhere..

    when i say no resistance I mean "open circuit" there is a "Data Link Connector" shown on circuit as X1 anyone know where it is located also A11 multi function control module?

    just wondering if ecu has power would the injectors still trigger even with no CAN line as the feeds to each injector coil come of master ecu?

    Just a thought.Could a glow plug relay short out without a fault code shutting the engine down? I think it’s easy enough to get to & replace

    Update I have tested the ecu pins k2 k4 k6 for ground all good k2 k3 k5 all show battery voltage. k65 k66 show 60.5 ohms on can data high all with ecu plugged in

    So you have power and grounds and can high data link . With 60.5 ohms so you have risistance which is correct .
    Have you ran a scan to see if you have communication with the ecu
    Because on the last photo you posted you had no communication to the ECU or the BCM or the transmission moduke.
    Which seems confusing because a manual gearbox would not have a control module.
    And in answer to your question ref the glowplug relay it would not immoberlise the car at all .
    I know this is going back somewhat, but have you checked the CPS to see if that is producing a pulse signal ?
