Sure, give it a try. It will either run or it won’t. You’ll either know what the problem is, or you won’t. Just swapping parts rarely fixes a problem.

I don’t think the engine will start, you will have an ID mismatch between the used PCM and the Immobilizer module.

There are seven different computers for your vehicle.

When I get a used computer locally, I have to provide the bar code of the old computer to acquire the correct one.
