First, whats everything and why did you replace it?

It is a fuel delivery issue. What is the actual fuel pressure? It should be greater than 55 lbs.

Ok, but you have fuel delivery issues. Thats why we start at the actual pressure. You can have "good pressure" as you put it but not enough to make it perform.
