Ok I?m gonna start a new thread with this problem.
I have been working on this truck of mine and some have been helping me with it. 04 Silverado. It in the last few weeks when I drive it the cluster would cut off all gauges go to zero. Then I could turn on the four ways and it would cut cluster back on. Now I can?t crank the truck at all I thought it was battery replaced and still nothing. I?ve checked fuses and took steering column apart checking wires. Now you can spin the truck over with mashing the relay together It when I try to scan the truck with hp tuners I get a message saying ( unable to detect vehicle?s diagnostics protocol ,it is possible that vehicle is not supported by vcm scanner. And possible controllers I. Vehicle are not responding for various reason )
So I am lost on what to do now. I?m leaning towards the computer is shot Please any advice will help
