Hi to all. I am new to this forum. I have a 1999 Chevy Tahoe with the 5.7 Vortec with over 283k miles on it. I have owned for over 2 1/2 years and a couple months ago, I began experiencing some rough idle issues. I have replaced just about all electrical components based on a crank/no start issue. There is compression and the fuel pressure is good. ther is no spark. I have just left the mechanic shop in Norfolk with the same conclusion as the mechanic in SC where I first broke down that the issue is no voltage signal coming out of the PCM/VCM computer. What I would like to know is if I purchase one from ebay or another supplier, is there a way to bypass the reprogramming or reflash of the computer? I am an active duty sailor, so any help here would be greatly appreciated.
