    To make a long story short: I replaced a leaking fuel line and now the ICE won't run for longer than 10 seconds and produces P0A0F and P3193 codes. I'm able to clear codes after letting it sit for an hour or so, but they come back after brief idle. Battery was disconnected in an attempt to "reset" things. No luck. Tank was at least half full when the Prius was parked and no further leakage was/is evident, therefore it's not really an out of fuel situation. More like the ICE isn't getting any.

    I wanted to keep it short, but will happily expand on anything mentioned above. I'm in a real jam, because the HV Battery state of charge will only go down with each attempt to start. I'm currently at 19%. By the way, HV modules read healthy.

    Any advice or guidance would be appreciated!

    Welcome to PriusChat!!
    DTC P0A0F has five (5) subcodes (they may help diagnose), which OBD2 scanner are you using that isn't offering the INFs (subcodes)?

    Here is the workup for DTC P0A0F with an INF (aka subcode or detail code) of 204, 205, 533, or 534
