    Seems to have a back feeding issue or something of the sort going on, has anyone had any similar issue with resolution?

    2012 Toyota tundra 5.7 sr5 trd.
    Don’t know much of the back story on it, purchased it recently.

    majority of time engine starts right up, occasionally it turns over 5-10 seconds and doesn’t fire up.

    When turning ignition off, engine stays running, dash stays on, everything else is off. Have to remove negative cable to shut it off.

    Replaced BCM, ignition cylinder, and electrical behind ignition, to no fix.
