Just installed a PCM from flagship one. Came programmed to the VIN. No crank and engine light is flashing roughly twice a second consistently. The old computer would start when it wanted, drive in limp mode, tell me my door was open when it wasn't, stabiltrac needed service, engine power reduced... you name it. With the new computer, I have no other lights on the dash except for the engine light flashing. Turned the key and all the regular lights come on then turn off. They advised me to do a key relearning process. It didn't change anything. I do not have the lockout light on, so I don't think its a key problem. I could be wrong. Any ideas as to me maybe missing a step or something I am overlooking? Key fob does lock and unlock the vehicle with new computer installed.
