Why did you replace the coil packs?

John has a good question. Somebody test them or just talked you into that? There are a multitude of things that will cause your car to not start, coil packs being one of them but far down the list.


Especially all 3 going bad. It sounds to me like its probably the crank sensor. They usually run only about 30-50 dollars and cause a no spark issue.
