I went on line and found a rebuilt computer for my P/Up $299 plus shipping
3 yr warranty I wonder how hard to change one out?
How do you know which one it is? Does your truck have an ECM, TCM, BCM?
Since you don't know anything about this, you're going to be dumping money down the drain. And re-furnished solid state devices like this are/could be suspect.
However, as suggested, open your ears and listen to the advice given by others.
Take it to the nearest parts store and borrow their code reader. Check codes, write them down and do a little research first.
I'm being a bit Sarcastic, but trying to lead you to the most efficient and least costly answer.
This is an ok place to ask mech advice, but better yet, get the codes and try a vehicle specific forum. And be prepared to provide some more info than "the tech said the whole thing is fried".
