Hey guys I'm having problems with my swap. I bought a custom harness to integrate my LS3 into my existing body harness, I was hoping that would fix things from the get go but it didn't. The car will start after some incredibly lengthy reset(Month or so), but after 6-7 starts it shuts down again. So I was thinking I had a VATS issue but HP tuners laughed at me cause it has a GM Crate Motor with a GMPP E63, they said it doesn't have VATS.. So I am a dummy...I was hoping someone here had ran into this problem before and could point me in the right direction.
