Thanks for those links. I check back my connections and did the procedures twice without any success. The H3 was not able to start but it has a strong crank.
The locksign goes out on the first attempt to start before starting to procedure and then it's not showing up again.

The battery is fully charged and I did change the terminals as the old one broken when I changed the battery

I'm not sure what else I could be testing for...

Any thoughts ?

 

I got myself a new acdelco ignition switch, did the procedure but unfortunately, the truck did not start. I also got a new set of codes P0223, P0315, P0335, P0365. After removing the codes with my OBD reader. The only codes remaining are P0223 (Throttle Position Sensor) and the P0315 for the crankshaft that needs to be relearn.

I will continue to see what else is stopping the truck from starting as the P0223 was never present until today.
