    The orange connector hasn't been touched, so it should be (doesn't look like there is anything wrong)

    So my options seem to be, spend $300-500 for a special charger, disassemble the pack to charge each cell individually, build my own charger, or take it to a shop?

    the vehicle doesn't have any way to provide power to the HV pack itself without the engine running?

    The problem code P0A0D for blocking has subcodes.
    The high-voltage system includes a high-voltage battery, high-voltage wiring, inverter, compressor for the air conditioner. Therefore, the subcode for the error will tell you the location of the problem more accurately.

    What high voltage skills do you have? Auto electrician skills?
    A lot depends on this.

    Until you find the location and point where the lock is broken, even with a charged battery, the hybrid system will not turn on. The Prius is designed to prevent accidental high voltage shock.

    no particular HV skills, I've done a lot of automotive and ham radio electrical, home outlet replacement, etc

    since the car was working before it ran out of gas and was driven until it stopped, there's a pretty good chance that it's only a low charge problem (there would have to be multiple failures in a very short time for anything else to go wrong)

    The fastest way is with the Prolong device or its homemade analogue.
    A high constant voltage of 240 volts and higher is supplied to the high-voltage battery.
    The charging current is 0.2-0.3 A. All modules are charged at once.

    Are you going to check the fuel pump????
    Running out of fuel for any electric fuel pump is bad because the fuel
    cols the pump, no fuel, no cooling, pump can burn up quickly.
    Since enough fuel was not installed, and you kept trying to start the car, it's likely
    the fuel pump is burned out.

    Manual applying voltage to the pump could tell you if the pump is at least running.

    You can "rig" different chargers to the hybrid batter to charge it, but it is highly risky.
    It's a DV battery, so if you have any experience with electricily, it's the same.
    You could do a search in your area for a hybrid shop that could possibly charge it
    for you, and test the fuel pump.

    Plus, with the Prolong charging/discharching system, you can run through the charge/discharge
    cycles and possibly bring new life to the hybrid battery which can help it last longer.

    I think I heard the fuel pump whir when I worked on it today. short of pulling out the back seat, is there a way to test the fuel pump?

    The hybrid battery was replaced in 2021, and the car isn't driven much (probably somewhere around 30 miles a week)

    Don't the dealerships have a special charger to charge a depleted HV battery? Why not bring the car to your dealership?

    Moving a car that won't start requires at least one horsepower))
