I'm not the expert that many here are but I do know that seeing fuel is not enough. Fuel pressure is critical as well. So if you can see both spark and fuel, and the car still won't start, figure that you're getting an insufficient amount of one of those - probably fuel. Good luck!!!

you need to check to see if fuel is getting to the intake. the easiest thing to pull is maybe the cold start valve. so pull that and turn on the key and crank and see if you have fuel squirting out. put a rag around it so you dont start a fire.
