You still haven't ever told us the exact problem.. I've read in to it that it simply "doesn't start".. but what else? symptoms, etc?
Can you hear the fuel pump prime the pressure on the system the first time you turn the key to "on"? (~1 sec. "whirrrrrrr" from under the rear seat)
have you checked fuel pressure via the schrader valve? (on the fuel rail itself, like a tire valve, most likely capped with a black plastic cap)
