OK, how about, you're car is almost 16 years old, and that's like 200 human years old. Time for a new one buddy.
someone wrote this on another site to my posting ...
[it sounds like you are on the right track. If it started up fine the next day, I think your relay is fine. Change your filter (because its easy) and if that doesn't work, it is most likely the fuel pump. It will be electric on a car that age and they do go out from time to time. The car is 16 years old and is probably just its time to go.]
What do you feel about that? [anybody]
