    2007 Prius, lots of miles

    ADDED 7 Gallons of GAS by hand from a metered Gasoline bottle.
    The engine will not start
    The fuel pump sounds to be running when I jump it
    I swapped out the fuel relay

    The car reports one flashing bar of fuel (incorrectly) As the gas was flowing back onto the ground, it is safe to say it is FULL.

    I guess what I want to know is if the gauge sender fails and decides there is no fuel, does the computer shut the motor down and prevent the fuel pump from running?

    And so....
    If this is the case, unless I find a wiring issue, I will need to replace the gas tank (unless I can get to the sender) I know there are screws around the pump and the pump cannot be removed, but is it possible to get at the sensor sender?

    I omitted the other errors, such as replace hybrid battery...that might make mechanic shops salivate, but I have a full set of cell spares...it just got tired as my daughter did not sense the engine had stopped and drained it....any one have a hand crank charger?

    No
    You need to determine the voltage of the hybrid battery. Use a scanner or a volt meter.

    EDIT:
    Does the car go into READY?

    Does the electric motor crank the engine?

    Has any maintenance/work recently been done? Please give us some history about the car.

    Please post all the trouble codes that the car has.

    I believe the primary problem is the engine will not start...the fuel sender has failed. The hybrid battery will charge once the engine runs. Barring that, I can charge the cells if need be

    Take a rubber mallet lay under the back of the car and beat on the bottom of the gas tank like you're beating a big base drum you're not trying to put a dent in the gas tank you're trying to shock the sender about eight good wax like tongfo kicking the columns and kickboxer the whole building shook. No see if showing full ,?

    I don't know that for sure. What I'm sure of is it changes the code you see: if the ECM was going to show you P3190 or P3191, but the combination meter thinks the fuel is out, it shows you P3193 instead.

    Whether that also prevents further starting attempts, I don't know.
