I have a 2008 P71 Crown Victoria Interceptor. 61,000 miles, runs great but sometimes turning the key I get all accessory power fine but clicking to start and there is no attempt at the starter engaging. If I pull it to neutral it will start right up. It's random, the car will start normally in park several times but then it won't even make an attempt in park and I'll have to shift to neutral and it starts right up. Any ideas to what may be causing this? Thanks
