    permanent P1671 code 2018 6.7 powerstroke

    Hi

    strange issue i?m having in one New 2018 Ford F450 6.7 powerstoke

    Check engine light Code P1671 secondary Fuel pump relay , dealer said that there was only one relay not secondary .

    the P1671 DTC is disabled in the ECM so i don?t know why the light is on , but there are many types of additional columns to choose from in the DTC , named from Type 1 to Type 9

    What can this be and what would solve this. Can?t find anything about a issue similuar to this.

    attached is the ECM file.
