I've been on here for awhile looking for answers... not much luck though... What does a "crank relay" do? Do they go bad and where is it in the car? What about the switch/sensor that knows the car is in park??? Don't know whats its called but do they go bad. I think if it was bad it wouldn't let the car start. I really don't think it's in the key because I'm not having any weird lights flashing on ther dash when I turn the key. Doesn't it at least try to start or turn over and cut off if the pass lock is tripped. How about starter issues... I had the battery checked and it had a full charge. I may have to take it to the dealer but I've read lots of stories about that... Any ideas????????????? thanks, Danny
