07 GT Wont Start After Tune?!
I had downloaded a tune for someone else vehicle into my car. After the tune was downloaded successfully and i went to start the car, the wrench light came on and the car didn't even crank. Battery is working fine.. What can this be? Tuner also isn't able to read vehicle any longer. Help?

Yes i did, then when i tried starting it is wouldn't even crank. I have done a lot of research and unfortunately I think the tuner might have fried my PCM. The car was 100% fine before i Installed the CAI and tune yesterday.

Wow, bad news. I'd probably start with a battery charger or jumpers, just to be sure that you are fully charged.
Where did you get the tuner? Did it give you a "complete" screen? How about when you took the tune out? Have you tried disconnecting the battery since loading the stock tune?

It says check charging system, and DTE ODO ERR on the dash. Would a not fully charged battery cause the electronics to go on but the car to not even crank? The tuner was bought unmarried from a friend. Made the mistake of loading his tune in my car instead of getting my own custom one. I tried disconnecting the battery twice, still nothing. I'm thinking I might have unplugged the tuner before taking the keys out. That might have fried my whole computer system. Not sure though.

You will need to replace the PCM or may be able to tow it to a dealer and get it reflashed to the stock tune.

JimC is correct. You will have to have your car towed to the dealer and have the PCM re-flashed to stock by them (I know, I did something similar). Then you will have to buy your own tune, giving the tuner the code from the PCM in your vehicle.

I figured it was the PCM. So once thats replaced. Ill have to download specific tunes to my car and then should all work smoothly? Does this have to be done at a dealership or can any service place (pep boys,auto zone) take care of this ?

You might be able to just have yours reflashed to stock - and the dealer will be the only one who will be able to pull a stock tune from Ford to reflash it. Pep Boys won't be able to get a tune. And if your PCM is too damaged and must be replaced, again Pep Boys won't be able to program it to your car and keys - so you are back to the dealer again.
