Truck won't start by ignition

0 votes
2016 GMC 3500 standard key  I installed EVO-ALL RS w/GMT5 stand alone.  It will start with the factory key fobs (lock, lock, lock) but will not start via the key in the ignition.  Once the ignition is turned to start, display advises "SERVICE THEFT DETERRENT SYSTEM".  EVO module is dark, when ignition is turned to ON yellow light activates.  When using key fob blue light flashes with each lock, then red light turns on, truck starts.  Once started red and yellow lights activate.  Any thoughts....?

Check fuses and connectors.

Check the DLIS fuse.

Did you reconnect the factory harnesses back into the t-harness and connect the t-harness in the original harness locations? Seen that a few times.

Thanks for the help it was the small connection at the ignition.  It was together but not connected.  Believe it happened while putting the column covers back on and moving the wires around.  Thanks for all the help.
