Okay so I was about to upload a tune using tunercats and i picked the change vin number option by mistake. I hit cancel so i didnt run the vin change. I then went to upload my tune and it didnt work. It kept failing. So I said let me completely turn the car on and off. All it did was crank and not turn on. I was thinking maybe the battery was low but i had just finished driving the car for a while. Im trying to determine if i fried the pcm when i hit vin number change even though i canceled it, if it is just a low battery problem or if it is something else? I had just driven the car so i dont know if it is the battery and i even tried turning it on with the battery booster connected.

 

anyone? what are the symptoms or a fried pcm?
