    Hello everyone I'm new here and new to Tundras. I'm having a no start issue on my 2000 3.4l v6 manual Tundra and so far have replaced the starter and the starter relay and tested the battery which is good. Next I'm looking at the crank sensor but I'm having trouble finding it and all the videos I see online are for the v8. Any help is appreciated

    V6 or V8, the crank sensor is driver side down by crank.

    Is it not turning over or not starting?

    It wasn't cranking at all, I read through some other threads on here and did some extra testing, I checked voltage on the battery and voltage drop on the battery connectors both were fine, then I checked to make sure the starter was grounded, it was. Then I tested the constant voltage to the starter which was good. Then I checked voltage from the trigger wire which was a little low, about 9.5-10v. From there I jumped the trigger wire and got it to engage and start. That was yesterday and it's still starting today.

    Starting with the key normally now, for the long term I'll probably look at replacing the trigger wire, or or try cleaning out any corrosion from the clip and to make sure enough voltage is getting there
