Starter keeps rolling after releasing key, and does not start. Hello, I have a 2004 Yukon XL, SLT, 5.3L with 160k on it. The truck runs great, and does not have any codes showing. This was an intermittent problem, but is getting worse, and is happening every time now. I think it is likely the ignition switch, but would like some second opinions before I order one. As I said, when I hit the key to start the engine, it just keeps rolling over, and does not start, and I have to turn the key to the off position to stop the starter motor. After the second or third attempt it starts fine, and runs perfectly. The part I am planning on ordering is called a " Genuine Ignition Lock Cylinder ", but I am not sure if it actually has the electrical contacts in it, or are those in another part?
Thanks for reading, and supplying any comments.
