    I'm having an issue with my Prius III.
    Initial push of button, turns the engine, but it does not keep running.
    I've checked: crank sensor- ok; cam sensor- ok; fuel pressure - ok; battery, both of them- both ok.

    I have replaced Cam sensor, throttle body, injectors, computer, replaced acid battery.
    Still will not stay running.
    Checked all electrical connections, all grounds connected, all look good.
    Everything has spark, but will not run.

    I don't know what is causing the issue, tried all I can think of.
    Anyone have a similar problem?

    Looking for assistance.
    Thanks in advance.
