2008 sierra, e38 possible vats issue
When the vats is armed on with a E38, does it not allow the starter to engage?
2008 gmc sierra (vortec max) owner swapped the L76 for a LY6, I was going to disable the DOD - Truck starter before hand, licensed the ECM, disabled the rear 02s and DOD - flashed the tune and no start, wont even attempt to crank. No fuel psi. So I figured the VATs enabled - I've disabled both VATs patches and starter fault check. No change, will not crank or power the fuel pump. Am I missing something with the VATs disable? Yes, I did "Write Entire"

You might need to do a security relearn. Is the security lamp/light on in the dash?
