    03 Yukon Putting 5.3 back in from attempted 6.0 swap now no spark

    Can anybody please look at this tune and tell me if I should have spark?
    I took on a failed attempted 5.3 to 6.0 swap ( They've been right all along and I really need to make better choices) So the 5.3 is back in, the p59 PCM that has factory OS (that I have a license to tune), segment swapped everything except VATS obviously and no spark. Is it something im missing? Before I start chasing down fuel pump relays and every other system needed to make it run, I figured I might start with the software. Since I don't know EXACTLY how things were configured I have nothing to refer back to. Just the file I've downloaded from the repository and swapped from.

    Hoping it's something obvious I'm overlooking. Any guidance would be humbly accepted. tune attached I hope.

    I don't see anything obvious in that tune that would not let it have spark. Start checking for power at the coil harnesses.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.
