    Hello,first sorry for my english I will do my best to describe the problem , last year I was crashed by an VW Passat at the side the right part of the car , the owner of the Passat have a very bad insurance only last mounth I can took the car to repair by myself because the insurance company is not any more and require more documents and legal actions .
    I took to Toyota delership for finding the damage,they give me a whole list of problems and mecanical problems,all the right parts was damaged , I change all the mecanical parts but the engine dosen't start , the hybrid sistem works I was able to go only on electric motor few feet to move the car after I change the mecanical parts , I took the car to a hybrid specialist and he told me is nothing wrong with coils,spark plugs,fuses stuff like that and maybe need a new computer , car works fine until the accident after the accident car dosen't start anymore ,maybe someone has experienced the same problem like me .
    The car stayed a lot in parking lot but the 12V battery is fine I will post all the cods Toyota give it to me .

    Thanks in andvance any help will be aprecied.

    There may be a problem with the High Voltage Battery- but you need to fix the P0351. Each of the 4 ignition coils sends a signal to the ECM when each one produces a spark. If any coil doesn't send a signal at all, the ECM will not allow the engine to run.

    It could have a bad coil, or damaged wiring. You have to check the IGF circuit from coil for cylinder 1 all the way back to the ECM (or try substituting a new coil).

    On my 2022 Prius Nightshade (and I assume on all other Gen4’s and earlier generations) there is an emergency shut off system that is activated when a severe impact accident occurs. The system isolates the hybrid system and stops the fuel pump.
    It requires resetting that my manual says must be done by the dealership. From your description of your accident, it is most likely what your problem is. Perhaps someone on here actually knows how to reset it.

    There's probably a setting for that in Toyota Techstream...

    Perhaps, I think what our OP friend needs though is something a little more definite. I’m reasonably certain that there is a reset button somewhere in the Prius, however, since I’m NOT CERTAIN, I await the input from someone who is.

    yes... I mention it because I've not seen the setting yet myself, but I bet others on here have and look forward to knowing.

    An auto mechanic who is a former electrician is well positioned for the electrification of cars. If I had a dollar for every auto mechanic who expressed fear of electricity in hybrid and BEVs I'd be able able to afford a Project Lithium pack!

    Well in my case was the stranges thing and maybe was only a coicidence or not , the problem was the LPG ECU , I haven't mention I also have a LPG system on the car and somehow the LPG ECU mess with the gas engine if I remove the fuse from LPG system car stars without any problem, tomorrow I will try the car to see if runs right .

    Well in the est part of Europe is a lot of hybrid Toyota or Lexus with a LPG conversion because here gas is very expensive for exemple now 1 litre of gas is almost 2$ and the LPG is less than 1$ so that's why a lot of people here convert their cars to LPG because of the cost , I don't have any problems with the engine or the LPG conversion this is the fist time but it's a cheap fix it's nothing expensive .
