2006 Prius won't start after running out of gas

welcome!
if you don't have a code reader, it's a tough guessing game. if you want to be cautious, pay the mech for the codes and post them here.

if he's good, the advice will be pretty much the same.

kind of odd that it started and drove after putting the gas in. did you notice the battery level?

 

I would check the replacement battery just to be sure it was not defective.

 

Did you by any chance mess with the Orange interlock on the HV battery?

There is some detail that must have been left out on the 12v death and subsequent change out.

Is there any power when you try to start it? Any dash lights? Headlights? Interior lights?

There is a common problem where the Gen2 cars have a bad combination meter and the entire dash lights go out. So this MAY seem like the car is not on, but if you wait 10 seconds, the engine will probably start without any dash lights.

Also since this all happened after changing the 12v, I would suspect maybe there is a loose connection.

But this all may be pointless since the car is already at a hybrid shop, they should know how to troubleshoot it.

 

i have heard of getting the codes cleared after running out of gas in some instances, not sure why.

maybe the battery is on its last legs and wouldn't turn the engine over anymore.

 

My bet is the hybrid battery is bad. This happens very often when you run out of gas the engine dies and your able to drive it for a while on the hybrid battery. Like it’s magic.

Sometimes people try to make t to the gas station in limp mode and that puts an extreme load on the already tired battery. It really heats up the battery and will expose a soft module. One module in 28 calls it a day the battery throws a delta nag and its nightly night for the battery.

Running out of gas in a Prius can be very expensive.

Without a hybrid capable code reader it’s all supposition.
If it was me I would get one ASAP so your not at the mercy of the dealer god help you.

Go to Amazon.com buy a VXDIAG with Toyota techstream. Works with a laptop it’s the same software the dealer uses. It will tell you exactly what the car is unhappy about and identify the bad modules.

 

There is still a chance the new 12v battery is bad. If it's been sitting on the shelf for a while, it could have drained. Getting a reading of over 12v right after you shut off the car doesn't have much meaning. It just seems very odd everything happened after the change out. I would load test that battery.

Did you accidentally connect the positive and negative terminals wrong? Even a split second?

Also Ed has a good point, running out of gas could have drained the HV battery and killed it.

The symptom of the car engine shuttering is not really a bad hv battery symptom, the engine should not be affected that quickly.

At this point you'll have to wait and see what the professionals say.

 

maybe some junk got stirred up from the bottom of the tank

 

I’ve run my 2005 out of gas turned off the ac and used the last of the battery to make it to a pump many, too many times. And once, when I had made it to within half a block to a station I waited a few minutes waiting for a tow to bring gas then decided to press start and go for it! Like you I had to push it the last 15 feet to the pump. Just as the tow arrived I was finishing filling the tank. Though when I pressed start, NOTHING! Not what I was used to. The AAA guy got his jumper battery out and we tried that too. And NOTHING!!!
Completely confused I got a tow home. And slept on it.
I found the next day when I disconnected the 12 volt battery it was low. So I charged it while I checked out some of the fuses and everything else I could imagine. I figured after 30 min I could reconnect the 12 volt and all codes would have been cleared. They were thou I noticed the dome light dimmed when I turned the headlamps on. So I figured the 12volt was still low and decided to use jump port at the front to be sure 12volts was there.
Everything came back to life and I made a post about it here on Prius chat. I read what happens to you and if I read correctly your situation is the same ran out of gas added some didn’t quite make it to the pump and drained the Hybrid battery’s then filling the tank you attempted to start it with a fresh 12 volt battery. You need to clear the codes by disconnecting the 12 volt. This will reboot the entire system.
Let us know.

The codes point to needing a new hybrid battery as well as poor engine power. So you are left with a difficult decision and the costs will not be cheap to get this running again.

 

The hybrid battery acts as a starter to the I C engine. Drain it low enough and you cannot turn the ICE with it. Remember the 12volt starts the Hybrid system ECU’s and not the engine. Those codes will be thrown 1 the battery has failed 2 the ice engine has no power and three the entire Hybrid system fails.
Fix the root problem by charging the hybrid battery and all the codes resolve themselves. 1 the 12 volt battery starts the ecu’s the the Hybrid system starts the Engine with Mg1 by holding Mg2 and rotating the crankshaft as a starter would. The engine will develope power within the timed window. And charging of the hybrid battery will commence as required by the hybrid system.

Does anyone know an easy a way to charge the hybrid battery without removing it from the vehicle?

With a grid charger, 24 hours
