Prius shuts down after Starting?

how many miles on her? any gas in the tank?

 

Be careful here ... the P3191 is correct, the engine never started. You thought it did, because a Prius cranks the engine at around 1200 rpm, fast enough most people who hear it think the engine started and then cut out. Nope, just being cranked, and then the system gives up.

Every such cycle uses a bit of charge from the HV battery, and you don't have an easy way to recharge that. So you are on a strict budget of starting attempts.

The reasons the engine might not start are the same usual three suspects: fuel, compression, or spark. So from here on out, you should be planning your remaining start attempts, and placement of your test instruments, such that each attempt will tell you something you don't yet know about one of those three things.

If you have any diagnostic tool (even a ScanGauge II, for example) with which you can watch the traction battery state of charge, you'll be able to have a better idea how much it drops on each attempt, and how many you might have left.

What obd device are you using? It should show more codes than that I don’t think your seeing the whole report,
You need a techstream device that has TIS software that will capture every single code and point you in the right direction. Without that you will have no where to start. Best you can do is check For gas check the 12 under load and All the fuses.

And yes the clock is ticking on engine start attempts.

 

Three threads, and running. The PriusChat search feature works quite well at the moment, it can be your friend in times of need.

Did you put gas in the tank? (4 gallons should do it)

First turn off the SKS (button under the steering wheel) and any interior lights that may illuminate if you open the doors. This could help save your 12V battery from draining further.

Here is a recent thread that might get you up to speed on things to think about:

Sudden loss of power, Red Triangle, Won't Start + P3190 | PriusChat

 

Did any of the codes have a “snow flake” icon just to the left of them? That icon will allow a deeper drill into the code. With the P0A0F, there should be some INF codes which will point you in the direction to go next.

If you can get those, I have a 2 day subscription active into tech info, so I could help once you get those sub codes.

Just don’t forget you are on a pitch count as there are only so many starts in the hv battery.

Good luck and keep us posted.

 

they all run for 10 to 15 seconds when you first start them and shut down..
does the car still move after the ICE shuts off?
what warning lights are on the dash?
give tampa hybrids a call, if he has the time the owner is very helpful and can walk you through what to check...

 

Just to clarify, there is only one 12v battery in a Prius.

The other battery is the HV traction battery which is over 200v.

Did you have a chance to read through the thread linked above, paying attention to post #9 (HV battery state of charge after reconnecting 12v battery) and post #14 (cleaning MAF and intake after reconnecting the 12v battery) and the work up for P3191 and P3190 in post #23.

What have you done so far, besides the 12v battery and adding gas?

At this point I would go slow with the repeated starting attempts, unless you have a way to recharge the HV traction battery. Once the HV battery is low enough it will no longer allow you to turn over the engine.

You might also be able to save some time/money by finding a qualified hybrid mechanic.

 

How many bars/color do you have on the battery display? Is it the original HV battery?

 

you said it runs if another car is jumping it... id jump it off another car and let it run to see if your hv battery is charging.. of course be sure ac radio lights are all turned off.. watch the display it should charge unless the charging system is fried.. might have rodent damage to the wires... id also take the 12 volt to autozone from a load test, odd are its bad.. resting voltage is meaningless if it drop drasticly under load..
did you call todd at tamp hybrids?

 

What were the INF sub codes (background data) that you keyed in on, that could help in solving the problem.

 

What is the State of Charge of the hybrid battery.

I would imagine it is quite low after all the starting attempts.

After recharging pack there are a few things you should do to increase possibility of the car startin.
Clean MAF
Clean throttle body
Sop up extra oil from below throttle body
Use some starting fluid down the throttle body when trying to start. Keep adding as necessary to keep it running until Prius takes over.

If youydecide not to tackle this yourself Tampa Hybrids will do a good job if you have them do it.

 

You didn't answer if it's the original but if it is...... be prepared for some bad news. Old, tired batteries don't like sitting unused. Once a month isn't enough. BTDT

GOOD LUCK

 

How did you charge the traction battery?
