Diesel container & the smell test

Easiest way is to access the fuel pump harness under the rear seat so you can power the pump to pump out the bad fuel.

The harness is under the thin metal plate cover under the back seat bottom. The plate cover is affixed with adhesive.

Carefully use a screwdriver or putty knife to pry the cover up. It will become slightly deformed when removing it.

When done with the job, form it close to its original shape before putting it back on.

Wear eye protection and fuel resistant gloves.
- Disconnect fuel line under the hood.
It is at ~40 psi pressure so be careful. You can wrap it with an old rag or towel while while disconnecting it to reduce amount spraying everywhere.
- Put a length of hose on the fuel line and run it into an appropriate fuel container.
- Provide 12v to the pump harness in the rear to run the pump until all the old fuel is out.
- Put in some new fuel.
- Pump through some of the new fuel to somewhat purge things further, disposing the fuel pumped through.
- Refill with fresh fuel.
- Reconnect fuel line under the hood.
- Clean up any spilled fuel.
- Reconnect harness under the seat.
- Replace rear harness cover.
- Replace rear seat.

I had a customer put diesel fuel in a Prius and she ran it. Not a good thing. She lucked out and it did not damage anything.

 

Do not try to start it with diesel in the tank.
You do not want to damage the engine or deplete the hybrid battery.
Hopefully the car will start right up once you get the correct fuel in it.

You could try starter fluid down the intake when first starting it.

 

His first post says the daughter ran it on diesel till it died then limped it off the road. Probaby killed the hybrid battery. We saw many of these years ago same scenario ran out of gas and drove it like a magic car on battery till the battery died. Back then the dealer had to get a 200 volt charger from Japan. Financial hilarity ensued.

Hybrid battery is what turns the electric motor MG1 in the trans that then spins up the combustion engine and that starts the motor. The car has no usual starter motor. So dead hybrid battery no engine turnover.

So your probably screwed. But continue on with Eric’s plan and flush out the system and then cross fingers it will start up. You have very few attempts if any at all left to turn the engine over.
Make sure they count.

They sell an auxiliary hybrid battery charger that you can charge the hybrid battery back up it requires installing a charge cable into the battery itself and you plug the charger into that cable. You may be able to just buy that cable install it and maybe borrow a charger from a fellow chatter. There’s many in LA. The really bad news is it’s very very bad to kill the hybrid battery to that level of discharge. It sometimes will kill it and at the very least it will severely shorten the life of that 11 year old battery.

Use Search Forum button up top and search. PROLONG CHARGER that’s the hybrid battery charger and also search

RAN OUT OF GAS. And HYBRID BATTERY

The website for the prolong charger is. Hybridautomotive.com

Good luck. You have a lot of work to do. I would make the daughter do it with you. She wont run out of gas again.

 

One thing to keep in mind, one big problem with diesel is the extremely low octane.

 

First, forgot to mention that the metal cover under the back seat has VERY SHARP EDGES! So be careful handling it.

After you remove that cover
Grey connector goes to the pump.
You have to push and hold open a tab on the connector to unlock it.
Then pull/lift the grey connector apart.

Looking down at the connector with the tab side nearest you.

There are 2 rows of 4 pins.
I'll arbitrarily call the position on the far left "1", position on far right "4"
Power can be applied to the pins in row "3".
For those 2 pins, apply positive to the pin in the row nearer the connector tab, negative to the pin in the row farther from the tab.

Unfortunately I don't have the colors handy.

Just did this procedure yesterday on a Prius yesterday so the position is fresh in my memory. ( As well as the cut on my finger.)

Feel free to call me with questions.

 

I could remember pin locations from memory, but not the colors.

Once you get Techstream up and running put the car in accessory mode and hook up the cable. No need to put the car in ready mode or start up the car yet.

Run a health check and then go to HV battery info and go to the live data tab.
Take some pics of the screens that show HV battery data. Battery SOC, voltage for each of the 14 battery blocks.

Hopefully battery SOC is above 20% else you'll have more problems on your hands.

If things check out ok, then move on to starting the car.

To get your best chance of starting I'd clean the MAF, sop up the oil in the intake underneath the throttle body, and clean the throttle body of needed.

Then use a little starter fluid down the intake when first trying to start the car. Squirt a bit as needed to keep it going until normal fuel delivery takes over.

Again, call me of you want me to explain some nuance to these instructions.

Or skip all this, say a little prayer, try to start the car and hope all goes well. You might get lucky... But if it were me I'd take the little bit of extra time so as to increase my chances of success.

 

Most people don't bother with the additional steps, and often get lucky.

But if you are the guy that is not lucky, then you kick yourself for being so lazy since you just bought yourself a world of hurt.

Pack looks good.
Keep on trucking.

 

Not sure what your looking at but Pack looks failed to me.The P0A80 was a good hint.

 

Edthefox,
You are correct.

I clearly was skimming and not look close enough at all 3 pics.
In second pic all blocks were ok and delta SOC was good as well.

But in pic 3 delta SOC is out if spec. At 38. Should be under 20. Even though there blocks aren't terrible, I wonder if you'd see larger voltage separation in voltage in the blocks over time at high/low SOC.

 

Thanks, @ericbecky . To clarify:

If you pop the cover of the connector you can see that the pins are numbered. Black (#3) is positive, White/Black is (#7 ) is negative. So, from my picture below, three down, left is positive, right is negative.

If you are draining the tank because diesel was put in by mistake I would suggest that after you pump it out you add some gas to dilute the remaining diesel then pump that out as well.

You will have to make your own electrical connection. I used a connector from a scrap car.

 

I have needed this photo for so long.......
