Then run a ground jumper to the blue with yellow and see if it will run. Is there any remote start or alarm systems installed?
I tried that, no start.
No remote start on the car.
Only thing aftermarket is the radio.
That makes no sense. You bypass the relay and you can make it run. Did you try a new relay? It is pretty simple system. Battery power to relay socket, Keyed power to coil side of relay, Ground signal from the pcm on the other coil side of the relay. Relay should latch and power goes to the item that needs to be powered up. Double check those feeds.
