I'm pretty confused by your post. If you had a VATS problem, motor wouldn't crank. You'd have no juice going to starter.
When you turn ignition ON, do you hear fuel pumps priming? If pumps are not running, it's because there's no signal from ECM indicating that you have ignition or Distributor Reference Pulse. Does the motor try to start and then die or simply not ignite at all?
