Check Hybrid System

Hello, last November I bought damaged (rear driver side corner) Prius 2010 from USA auction and shipped to my country. Yesterday all repair jobs were completed and today we tried to move it to service (to prepare for technical inspection) but encountered problem:
Screen shows "Check Hybrid System". We can start it but after up to 10 seconds engine and car shuts down. Hybrid battery is almost empty (only 1 bar). What can cause it?

 

Mechanic doesn't said very much, only "ignition problem". But engine for short period starts.

 

When car arrived in my country we were not able to start it (even locks was not working) so we charged it. Then we were able to start and drive a car. After repairing fender, trailer transported car to this service where car was repainted. After transporting, my father tried to start a car but it was making loud rattling noise but after short period of time it stopped and engine was working fine again. First mechanic was able to drive it out of his garage (he said that is was really silent).
During repair process 12V and hybrid batteries was disconnected but as father said he checked if everything was connected properly this time.

 

Car has 84k miles on it

 

Thank you, we took 12V and left it to charge overnight, tomorrow we will check for HV again.

 

Big thanks for this page. I see that service history ends in 2014 (32k miles) (now it has 84k and really dirty interior :/ ). During history mainly oil changes and tires rotation but there is one record about recall. Also site shows that there is one more recall. About second one I find out while car was still in the middle of ocean. I wrote letters for my local dealer about it. I received answer that this car is not made for Europe market so they need to send request for Toyota and this might take more than one month.

 

This morning mechanic inserted battery which was left to charge overnight and as they said, they were able to start the engine and drive it outside in reverse (while in reverse car switched into EV mode) but after getting it outside after short period of time car shut off (completely).
Today another mechanic checked failure codes and he got P3190 and some other but after deletion only this one appeared. Father tried to fill some gasoline (~5 liters = ~1,3 US gallons) but after few attempts no good news. I'm out of town today so I will be able to check it only tomorrow or Monday.

 

Update: yesterday I've read a lot about other prius'es getting same error code and found out some problems which may cause this behavior: low gasoline level, fuel pump, MAF, too much oil. Today we checked that oil level is at MAX level. My father took some parts of the engine and we find some oil in intake manifold (see pictures below). Now dad is cleaning it.

 

Unfortunately after cleaning intake manifold, car is still not mooving. First time it tried to ignite, was working for a few seconds and shut off, second time it is not even trying to ignite the engine. Now we are waiting for mechanic to read error

When connected car showed 4 codes: P3190, P3191, P3000 and P0a0f (last two was in hybrid section). After deleting them, I tried to start it but it sounded like I would try to start a regular car with starter (it tried to start only for a second and then shut off). HV battery shows only 1 bar so maybe it is possible that it has not enough power to start that engine? Maybe there is simple way to charge it at home? Or we need to ask for help from dealers?

Next week we are going to check fuel pump and spark plugs. Maybe there is something else we can check ourselves?

 

Update:
Yesterday mechanic drained about 3 l of liquid (probably water) in gas tank. But he was not able to start the engine. So he took 12V to charge overnight. Today mechanic fully drained gas tank and entire fuel system. After that engine started and battery well charged. Start was harsh but not for long. Now it starts and runs well.

Not much left until I will be able to drive it (need few additions to pass certification before car registration).
