    I replaced my injectors and now I can’t get Prius to start.
    It will try and start but then it quits and the HUD says check hybrid system stop the vehicle in a safe place
    I also put a new 12v battery in but it have 12v when I check it.
    Anyone have any clue what’s wrong

    12v may be too low for a new battery. charge it up, and measure the voltage at the jump point under the hood

    Any lights on the dash? Error codes? Symptoms prior to you working on it? Seems like the electrical signal that fires the injectors are not properly connected if the problem was caused by you working on it. But that's just a wild guess... And sometimes totally separate problems show up soon as you fix the existing concern.

    If it started before and now it doesn't? It's most likely something you did? What was the last change? The Battery or the Fuel injectors?

    You to double check your work. Is everything hooked up correctly? And if it is, it's not impossible to get new part's that don't work. It's not the norm but some times crap happens?

    You could also reinstall the old parts or get a OBD II, Dongle and a Phone App and pull the codes to see what's up?

    Did you ever figure out what happened? My gen 3 is now doing the exact thing after fuel injectors were replaced.
