Ecu connectors back in the right order? Does the car start with the factory ECU?

i didn’t clone just did the partial unlock and the plus are all in order as well going to try disconnecting the battery

dark picture is how the plugs were and picture in the sun is how i reconnected

Look at the connectors from the sides and see if all the connectors are leveled. That's the best way to tell if they are fully secured.

Slam the connectors in even when they click they aren’t always all the way down I had the same thing happen throwing a bunch of codes when I pulled my ecu to check the date

Those connects are a pain to set back in properly pull at each other lightly to make sure they are fully in

Correct order.

Undo them and check again.

Sounds like a brick but they can be slightly unseated.

Did you check the dme serial before and after you sent it in?

Literally same thing happened to me and I had to take all the connectors off twice to make sure they were fully clipped in. There were a couple that clicked in but they really were not locked in and pulled off super easy even after seating them flush and snapping down the hinge.

Hey guys thank you for all the help the connectors were clicking when pushing them down but wasn’t actually connecting. After reading a few comments and asking a few friends turns out i had to push them down and make sure it’s level with the others to ensure it made connection after that car started right up with no issues
