    Swapped ECM's, did write entire no VATS now no spark?

    Hi Guys, 06 C6 Z, thinking might I have a bad ecm so I grabbed a ECM from an 08, Swapped it, rewrote the tune and disabled VATS, did a write entire. Now the car will turn over but not start, it's not getting any spark and I am not seeing any rpm while cranking. Any ideas what I could of done wrong?

    TIA!
