I assume we are talking about a TBI motor here. Am I correct?

If so, then I would start by verifying that you are getting the proper fuel pressure to the throttle body. You say that you have verified that you have fuel to the throttle body, but the presence of fuel and appropriate fuel pressure are not one in the same.

While someone is attempting to start the motor, can you see fuel spraying out of the injectors?
