broke down with a P3190

That's all normal.

 

Since no one asked how old is the 12v battery then I won’t

 

Normal ... and that 14.2 to 14.5 is the DC/DC converter output voltage, not the battery voltage, and the fuel pump is running on that, not battery voltage, when the engine is trying to start. (The fuel pump probably can run just fine, right down to 10 volts or so, just 'cause I'm pretty sure they're using a pump they could also use in gassers where it would have to run while the 12 volt battery cranked the engine. But in a Prius it's not ever likely to see any voltage that low.)

So I don't think a "battery too low to run fuel pump" hypothesis gets much traction.

 

If you only put 1 gallon of gas in your car, fill a gas can and bring it with you. Try to drive 50 miles, if you run out again before 50, then you know the gas meter is probably wrong.

 

Chapman is right and you are not qualified to make this diagnosis since you do not know the basics of how to diagnose which of the gas engine systems is it fault. You will run the traction battery down to the point that you can no longer attempt to start this car and you'll have to charge the battery separately in order to attempt this again. Although I can give you the most common cause I have found for this problem It is likely not going to help you because you do not know all the diagnostic approaches and I cannot teach them here. Do yourself a favor and hand this car over to somebody highly qualified to do the repair for you.

Had to fix another shops blender on a Lexus CT 200h. Clearwater hybrids put in a used fuel pump and it didn't fix the problem. Didn't do proper diagnostics and they used fuel pump with seized just like the first fuel pump. I have to question if they even replace the fuel pump with a used one as this is what was relayed to me and the accuracy and her information cannot be trusted because it's secondhand and because of the person relaying it. They could have pulled out their fuel pump that they put in or they could have put in another bad one or they could have never replaced it. Any combination exists. Since the OEM fuel pump comes with the level indicator assembly and that whole assembly is around $800 at the dealer it's also possible that the car owner declined repair and didn't tell me the truth and just blames the servicing shop for failure to repair. In any case the fuel pump was seized in place. But because they tried to start the car so many times they ran the battery down to nothing and I wound up replacing the battery pack as well. So what started out as an $800 fuel pump plus labor turned into several thousand dollars for a fuel pump the labor the leaking gasket because they destroyed the fuel pump tank gasket a replacement hybrid battery and the reassembly of the entire interior of the car which they never needed to take apart.

Manually manipulating the throttle vane oftentimes results in the need to recalibrate. You may have destroyed this part and MAY now need to REPLACE.

I've even gotten that code when I worked on a Prius v and it had a bad inverter converter. I take it you don't have a dealer computer. Abort this job. You're making matters worse.

 

already happened ... OP has some ability to put charge back in the battery (post #10).

Doesn't seem to be doing too bad a job ... I've only cautioned about focusing too early on specific possible causes, before testing has led there.

 

The next domino to fall is now the fuel pump since it was starved of gasoline. Gasoline keeps it lubed, without gasoline it slowly burns up.

 

Any time there's a party that needs livening up ....

 

A bad fuel pump which is seized in place offers no fuel pressure. The engine will crank for 7 seconds and sound like an engine that is running but it actually is not. You will get that p3190 code that you got. Bidirectional scanner like the dealer computer offers you the ability to switch the fuel pump off and on for testing purposes

 

The level float in the [pump assy, gas] oftentimes hangs up on the contour of the tank if the person who installed it doesn't have the alignment right

 

It's probably a good idea to not let the level get below 1/4 of a tank.
Since I do a lot of highway driving and about 700 miles a week I fill up
at half a tank. Or as close as possible. If I get stuck on the interstate because
of a wreck, I'd rather have as much fuel as possible.
And don't rely on the fuel gauge. Keep track on your mileage, and mpg.
Then you'll know you have "x" amount of miles per tank and you won't run dry.

You might want to start saving up for a fuel pump. Just in case running it dry and
trying to start it so many times you damaged it, shortening it's life.

I hope that your problem is resolved!

 

Life happens!
I always look for the simplist and easiest things first....

The faster, more volume flow was probably enough to break it free so it could move....

 

You have to get silicone grease from the pool supply store and the pictorial online. There's a lineup indicator on the pump /level assembly and the gas tank. Apply a lot of silicone lube to the large o-ring. Other greases react with the gasoline

 

Hello can any one help me on why the relay for my hv blower is below 3.9v and not 12v I hear the relay clicking but the fan won’t turn on
