2003 GMC Sierra 2500 HD Base 8 Cyl 6.6L
2003 to 2007 6.6 diesel
I have 2003 cab I set this cab on a2007 frame with motor now it doesn't want to turn on it crank but it won't turn on
My question would be what computers and ignition did you use? If the computers are not match within there programming the vats / theft system will not let the vehicle start.
