Ok I'll take a stab at this one...
First

id the car die on you on the road or did you do some work to it and now it doesn't start(I know why ask,but this has happened in the past)
2:How do you know its getting proper fuel pressure?
3:What color is the spark when you checked it?
Have you checked to see if the timing belt is broken?
Does the engine turn over(crank)
