I have a 2007 Crossfire that won't start. When I go start it it won't crank. I can try it several hours later it'll start. I've taken it to the dealership, left there for weeks at a time and it always start while there. I've replaced the starter switch and clutch safety switch, yet with no positive results. Any ideas what the problem might be? From November until yesterday it would start, yesterday nothing, this morning nothing.
