Odd problem?

I have a 2000 Grand Prix GTP it has 129,000 miles on it and it runs good never gives me any trouble. Change the oil ever 3500 miles try to take good care of it. Until now went out to go to work and it would not start. It would turn over but not fire. Tried a couple of times then gave up. Came home after work and went out to try it again and it started right up no problem. Any body ever have this one before? Skiffer

What does it do now? How old is the fuel filter? Have you run a check of fuel pressure to see if it is in specs?

It is running fine now. But I will change the fuel filter it has been a long time. And also will check the fuel pressure. Thanks
