Hi, i bought a new ecm, or ecc module, but my cooling fan ran at the right time before i bought it. Now it doesnt run and i was wondering if anyone knew anything about it?

no this ecm is for this vehicle, and is new from a autozone store. But i took the chip out of the other ecm and put it into the new one, so it should have the same programable memory?
