    One
    Woke up one morning 12v drained.
    Replaced battery.
    Car starts. Runs for a few seconds stops
    all fuel bars flash.
    Will not restart.
    No codes thrown.
    2001.

    Reset fuel gauge with odo 3 presses
    Cleaned mass air and throttle body sensors
    They looked clean
    Washed engine. No broken wires.
    No obvious blown fuses
    12.4 v on aux battery.

    Can repeat symptoms. Pull black cable on pos of aux battery
    Starts once. Runs for a few seconds. Stops all bars on fuel gauge flash.
    Will not start again.

    If I had to guess fuel sensor tells ecu no fuel pressure. How do I test that?
