Check if the injectors are squirting fuel--if not check the ignition pick-up coil in the distributor

If it starts when you put fuel in the TB, then it is a fuel related problem. Have you confirmed that the fuel pressure is within the manufacturer's specs? Have you checked to make sure the injectors are getting power? Did you flush out the fuel line and fuel rail?
