    6.0 swap no start

    I swapped 6.0 lq9 to 1999 corvette

    It cranks but no start.

    I have confirmed fuel rail pressure and spark.

    Should ckp be reading 6000 to 6300? I had to fix wires there

    Assuming ckp is good since I get rpm reading?

    Here is link to log

    Most people on here won’t download linked files. They ca
    N be attached directly in the forum. And you need to post the tune.

    Have you confirmed injectors are firing? I would expect it to start if this is just a block swap. What other parts are from the lq9?

    I dint have an injector light to test but they must be. Plugs get wet and smells like fuel after too much cranking

    I went from 5.7 aluminum with unknown choppy cam to 6.0 iron block with torquer v4.

    Id assume it should still fire with same Tune. It cant be that much different. As far as I know it was running on stock Tune with just idle adjustments but motor was smoking since I purchased

    Original from the 5.7. I think they are 24lb

    Everything migrated over except the block crank pistons and rods.

    Stupid mistake. Intakr and coolant temp sensors pins were bent. Fixed them and fires right up.
