I used Tunerpro to edit 12587603 bin file. Disabled VATS and uploaded the bin to my ECM (Hardware# 12589162). Bin 12587603 was not my original operating system for my ECM. I attempted to start my engine and the engine would not start and run. I then installed my ECM inside a friends 2004 silverado. The truck's security light came on and went off as the engine started and ran perfectly. I removed my ECM from my friends truck and installed on my engine again. My engine still does not start. I am using the original harness and engine from my donor 2005 silverado truck. When the ECM is powered on with "key" power, I do not get power to the fuel pump from the ECM. I can manually supply power to the fuel pump and still no start for the engine. The engine acts as if VATS is "enabled". I checked the VATS settings with Tunerpro once again and observe VATS to be disabled. I have extra ground cables attached to the engine.
Any ideas as to what I am doing wrong to get the engine to start?
The bin file I uploaded to my ECM is attached to this thread.
