So my mustang is doing something unusual. When I turn the key to the first position (on) it cranks the engine. When I turn it back to the accessory position it also cranks. I'm thinking ignition switch is bad, but here's the thing: The car has been in my garage for 2 months during which time I have done a lot of work on it. T5 conversion, installed dual exhaust, replaced washer pump, replaced headlights, new fuel sending unit, and a lot of other little odds and ends. I really haven't done any major electrical work, mostly just changing out parts, and I'm pretty sure I didn't change anything (other than bypassing the neutral safety switch). I find it strange that the ignition switch would go bad while just sitting in the garage, but I'm sure its possible. Can you guys think of anything else that could cause this?
