2008 Prius wont start, newbie, trying to help an old friend

So, I am somewhat mechanically inclined, do most of my own mechanic work all my life. I have a 30 year friend with a 2008 Prius with 212K that stranded him in Northeast GA. Nearest dealer is 40 miles away. He asked for my help in getting it to go back to FL. When I first looked at it the 12V was dead (no stored codes) I charged it up (2 yr old batt) now shows 12.7 and the car tried to start (Electric spun ICE) but no start. Found throttle body stuck. Cleaned that thoroughly. Used computer to clear codes. ICE spun again, but no start. Got Red Triangle, and codes C1259, C1310, P3000, POA80. Hybrid batt bouncing from 164V to 170V. It is obvious it needs new hybrid batt. But should it still start the ICE??

 

I should add that I am using my typical code reader that will not pull the toyo specific codes. I will have my other reader and pull the toyo codes in the am with Torq pro, so we don't waste too much time. Just wondering if ICE will start once ICU reads low or varying voltage from Batt pak? I am not very familiar with the Toyo Prii. Own 6 other toyos' though. Mostly 4.7's - don't get nearly the MPG, but got lots of Zoom!

 

Hi guys, thanks for the input! Sorry I was off grid last night... No, it's not on the side of the road. It drove to where I picked it up. Sat for four weeks n the 12v was dead. As I said, it's fairly new and I charged that.

 

Ice spins after resetting codes, but doesn't start. I don't know any service history. Maybe fuel pump?

 

Thanks Guys! I am gonna pull a plug and see how they look. I picked up a used main batt this am for $50 that is showing 208V. I know it is an unloaded reading, but it was cheap enough, I thought I would give it a shot. After I pull a plug and check it, I will put it in and see what results I get.
