I would start by checking fuel supply and ignition. I would also have my engine codes read.

check fuel pressure if its a port fuel injected engine it will require 55 psi minimum to start the fact that fuel is coming out of the filter doesnt really tell you anything, a weak pump may be capable of producing 50 psi and cause a no start condition.
