Hi all, I just bought my son this truck. It doesn’t start. The previous owner have the ECM on the floor in the cab, he said it needs to be replaced. I checked with dealership, it’s not OEM judging by the part number. I can’t find one to replace it with anywhere. I’m worried if I send the one that was in the cab of the truck out to be rebuilt, it will come back and be the wrong one. It’s about $350 to send it out. Should I call around to junk yards to try to find one with the correct part number on it and send that one out? What do I do if I can’t find one? I called 4 parts stores and a local dealership already. Any suggestions? Thank you!
