When i bought the V8 swap it came with the ecu and all connected. I tried too start the truck today and nothing. Starter dont turn over or anything.Theirs a key lock and car light on the guage cluster, that turns on when trying too start the truck. Do i need to get the key programmed or anything for the new ecu?
I installed my v6 ecu back into the truck, it does the same thing.
As far as i can tell everything is connected and installed correctly am i missing something?

Thanks
