Power everywhere, no crank

[Redandblackchevelle]

Not my first LS swap have one completed in my 1970 Chevelle. Got a two door 96 Tahoe Got the engine and trans mated. The harness and computer all set up and come on and off with no issues. I try to turn the key but getting no signal to the starter. Using the original truck ignition for signal. I have a brand new NSS switch installed using the factory plugs. Running a 2002 5.3 with a newer 4L60E Trans. What am I missing? Have the power wire from the battery on the positive post on the starter. And the purple wire attached to this small stud. Have ground running everywhere to the frame and firewall and body. Kind of stumped right now

VATS disabled ?

VATS disabled ?

Yes that is disabled. The problem is I'm using the original ignition and computer to start the car. Shouldn't be a problem but its not sending a signal to the starter, have power at the starter relay

if you have no ground to the coil for the starter relay from the computer maybe a bad neutral safety switch, or maybe not in park,or the linkage is not in the correct position. try to jump wire straight to the starter from the ignition

On my '81 I just used the original purple wire to the starter.
