Chevy Trailblazer 2003 V6 2wd...wont start

have an issue with my 03 trailblazer. i have the problem of no start when key turned to start position. actually nothing happens when the key is turned to start position. dash comes on when key is turned to on pos tho. took battery off and had it tested and it is at full charge. took starter off and had it tested and it passed. checked ignition relay cavities per this youtube video “Chevy Trailblazer no crank testing and information” and there is no light when touching the ground request cavity and turning the key to start position. i’m stuck here lol. any thoughts?

Is the security light on? Any after market remote starter, radio etc?

Auto transmission? Try shifting to neutral and try that. If it starts…you probably have a bad neutral safety switch.

no aftermarket remote starter and i did try shifting to neutral and still no luck…
