2000 chevy geo spark & fuel... but won't start

[saxxxu]

Hello guys first of all hi to everyone in this helpful forum, I got a 2000 chevy geo that won't start for some strange reason I have good spark and good fuel pressure I even replaced the in tank fuel pump and filter as well as the relay, it seems klike if the injectors weren't pulsing but when I spray starter fluid it will start right up and will stay on with no problems or fuel starvation under aceleration, any clues? Thank you
