I recently changed the motor because the motor started knocking on the last one, Now my problem is the ecu is not getting power and the brake lights stay on as if I have my foot on the brake. I have double checked all my wiring and grounds, changed bcm and ecu.
Do you
have the same problem?

You need to check all fuses, especially the fuse for the ebcm ( electronic brake control module), fuse number 35 I think. Also you need to verify that you have communication with a scan tool and see if there are any codes stored.

I will check that fuse right now, but I have gotten a scanner and it doesn't read the computer at all?

Ok, that helps. Make sure that you check every fuse in both fuse boxes very carefully and again especially the ebcm fuse. If you find any blown, first see if that restores the scanner communication and check for codes and post them here for me if there are any. Let me know.

I have checked every fuse and the only fuse that doesn't get power is the BCM fuse it is a 10. I swapped it out even though it wasnt blown and it still doesnt have power, I keep checking with the scanner and it still doesnt read anything

That's what I suspected, in all likeliness you have a faulty module, but I would suggest that you have it diagnosed by a shop to be certain.

I am going to have to recommend that you take it to a shop and have it diagnosed, it is to costly to keep guessing.
