Still has the TPI I assume? When it won't start, does it have spark? Does the fuel pressure hold when you shut it off?

If it has spark and FP, all that's really left is to fire the injectors. Have you tried reseating the ECM connector? How about cleaning the grounds on the back of the passenger side head?
