    hello friends I have a bad feeling about this car I bought it 2 weeks ago I thought the battery pack was bad I fixed the battery so now I turn the ignition get the ready sign and the engine shakes like is falling apart lost of noises
    this is a YouTube video unfortunately somebody called me during the engine start and is kinda hard to appreciate but the noise is there. I feel like maybe there's no fuel pressure , where should I start diagnosing??

    I'd have to think the engine light is on so get all the codes first (preferably using Toyota's Techstream software). How did you "fix" the "battery pack"? I'm assuming you mean the large traction battery rather than 12V. The traction battery is what starts the engine and it is clearly trying it seems. Sure doesn't sound good, but I'm not familiar with the specifics of the starting system on the Prius.

    Thanks for the reply , yes I fixed the traction battery I bought this car cheap because I thought that was the problem, so I fixed the battery installed it and now the car is doing this weird self destructive misfire, I've got to the conclusion that the battery was never bad the problem was the previous owner tried so much to turn the car that drained the traction battery now the question is what is wrong with the car.

    Since you have the head off already, I'd be included to say give a new gasket a go.

    Also, since you already have the head off, you might want to look at this thread and possibly search others like it here at Priuschat . EGR Maintenance | PriusChat

    From what I've read about it the two are almost always related one two the other.

    Good to know thanks I definitely will take a look at the egr I think I'll buy the engine I got a deal for $350 and 6 month warranty I think this will be cheaper than doing the repair

    the only risk in replacing the head gasket is other engine damage. pistons, rods, crankshaft, warped head, etc.
    when you catch it early on your own car, new gasket no problem.
