    or there's a breach in the wiring.

    I saw one guy on here a while back who, at the connector/junction (under the cab?) feeding power to the fuel pump, corrosion caused a drop in the line.

    I saw another guy on here whose flex loom got pinched by the cab or the bed, and it chewed thru/shorted the power wire.

    This is easy enough to test for, download the EWD for that year, which is posted here. Find the wire color, and trace it back until you hit the junction where it gets power.

    I'd start at the relay socket, jumpering power there. If it's not getting power, the ECU is either not triggering the relay, or there's another issue with power delivery to the relay, if I remember the wiring correctly.

    Thanks for the intel. I will start looking. the Efi relay/socket gets 12v when cranking….
    So must be between the fuse box and pump….

    The attached pdf for a 2006 Tundra Fuel Pump Circuit may or may not help....
