G37 is automatic and push-to-start. I have installed the T-harness and programmed the Evo successfully multiple times. I tried different options with the Flash link updater as well.
While monitoring the Evo's LEDs, I can see the blue LED flash with each lock press. After the third press the red LED comes on for a second and the brake lights come on. Red LED flashes a few more times like it's trying to start but to no avail. It repeats this process for 2 or three times I think.
If I hit lock x3 while the key fob is in the vehicle, it starts right up.
I have double checked all my connections. Considering that it's a T-harness, this shouldn't be an issue.
