    Hi I'm new here
    I bought an old cab, 2012 v, and it held up well for a bit. But got missing codes so changed the injectors. Now it turns over but not for long enough to start the motor. So I'm looking here for help. Can I manually start the engine? Can't hold the key longer lol
    Haven't found the answer yet, but I'll keep looking.

    Have you checked fuel pressure and make sure you're having enough fuel to the engine?

    The injectors didn't fix it... A Prius engine not starting is much different than regular cars. Your description indicates the engine still won't start. And if you don't have a way to charge up the high voltage battery you have a limited number of attempts to get the engine started before the hybrid battery doesn't have enough charge to do it. So it's time to be thorough...

    How do the spark plugs look? Engine oil and exhaust smell different than usual? Also what device are you using to read error codes? Many devices give bad readings from Prius. Dr. Prius app via an OBD2 reader is easiest way: Hybrid battery diagnostic and repair tool for Toyota and Lexus

    Welcome to PriusChat!!
    How many miles on the old cab ?
    Could you please share with the rest of us those OBD2 codes (DTCs) ?

    Did you buy new or reconditioned replacement injectors ?

    Did you inspect the plugs and or coils for carbon tracking or oil fouling ?

    Thank you all for your suggestions.
    The car has 600,00 km on it. I was assured it was well looked after but no papers proving it. It ran well, until it didn't. Found a second issue with a broken coolant fitting. Waiting for that part, then try again.
    Is there a way to charge the hybrid battery, besides towing to dealer? I may have asked too much of mine and sitting like that for so long, 2 months now, I'm starting to doubt.

    Without knowing the DTCs (OBD2 codes) it makes it difficult to offer guidance, what device are you using to retrieve the codes with?
    Most would use a commercial product like Prolong or Maxxvolts, others may use HV LED power supplies or Electrophoresis power supplies.

    You'll probably be all right. Take lots of turning the motor to drain battery...

    High voltage trickle chargers made by Maxx Volts, Hybrid Automotive and others are in the $200 - $500 range and you can also build one yourself if you have basic electrical knowledge as per this post:

    Another option is a hobby charger w/NIMH algorithm and you can charge up each individual 8.2 volt module, of which there are 28 of them.
