Hey Tom, thanks for the tidbit. Do you mean the DLC3 jumper registration as described in the workshop manual or a TechStream registration..?

At first I didn’t think the DLC method would work at all, but if your engine ran for 15 seconds it must have worked on some level. I say this because every single ECM swap I’ve done, the engine fires up for maybe 2-3 seconds and dies. After that it will only crank and never run again until you disconnect the battery.

The only fix I’ve ever seen was to bypass the IM module if you have a non-IM ECM, or to register completely via the dealership process. I’ve hear of people getting the donor cars IM module and key to make it work as well.

Another thing to consider is those guys that come and cut keys for you, I’ve heard they have a way to register keys.
