Hello, my chevy uplander has been giving me the blues. Lately, when I put the key in the ignition and turn, nothing happens. Absolutely nothing! There's no sound at all. It doesn't try to turn over, grind, nothing. I have gotten the battery charged, the starter tested and the alternator replaced. Sometimes after letting it sit until the next day, it will start right up. There's never a warning when it decides that it's not going to start, it just doesn't. I think it may be an electrical shortage somewhere. What does that sound like to you?
