V6Z06Swapper

I do not get any spark while cranking the motor! i have new MSD on a new LS6 in my camaro. i am using a painless harness. i had a my junk yard computer go bad so i got a brand new one from the GM and had it flashed and tuned. installed that computer and now i dont get any spark. my tunner said that everything is working right on his end (RPM, power, gnds etc..) so he said check your car and call me back. i have tested everything i can think of like CPK..and CMP.. all the wires going to the Coils. checked grounds. not sure how to check the coil packs with the meter but i would never think that i would lose 8 MSD coils?? .. i was thinking maybe something to do with the VATS on the painless ..that doesnt like the new computer? im kinda stumped?
please help!

Thanks kurtis
