    As the title says I can get my 2010 Prius into Ready mode. The car moves under electrical power

    But the ICE never starts

    It was driving fine the day before and today this happens

    I took a volt meter and check all the voltages of the coil packs and the injectors and the harness do not show any voltage to those items

    I have switched out the crank position sensor with a new aftermarket one from ebay

    I also check the fuses and cannot find any blown fuses

    Has anyone encountered this issue?

    Can you please explain why you replaced the crank position sensor?

    When did you replace it?

    There can be many reasons why the petrol engine does not turn on.
    As a rule, a malfunction icon appears on the dashboard and you can read the problem code with a scanner.
    Can you attach a photo of the dashboard?
