Okay, that means it at least is seeing the key as valid. Now we need to figure out why the switch start signal isn't getting to the relay. For that, verify that the start pin 3 on the switch is sending battery voltage when you turn it to start. If it does then go to the Body Control module and verify that the same signal is there on pin B8 in connector2 If it is then great, if not then that wire is open someplace. If it's good then check pin B6 in connector number 1 for the same signal. If its there good, if not then the BCM has an internal problem as they should be linked. From there it goes out to the start relay. If no signal at the relay the wire has an issue.
