It seems to happen more often when the temperature is below 40 degree F. It is very random and will start fine for weeks and then all of a sudden it wont start. What it does sometimes is starts right up for a second or two and then just quits and it wont start again. I have been getting stuck with this problem for the past 6 years and even my mechanic can't find the problem because it starts up for him! Please help!!!!!
