you say cranked 6 or 7 times and no start. As in dead battery no start. Like it runs down the battery or am I wrong here? I had an issue with this once, and it was the corroded connections on the battery terminals. They looked clean but weren't clean enough as it turned out. I also will assume you have disconnected the battery and reconnected it. Just sounds electrical to me. Check ground wires, especially to the starter...
