So you have a fuel delivery problem ...
Could be an empty tank, a defective pump, no power to the pump, a clogged filter, or injection issues - the reason I'm suggesting a pressure test is you could have a pump that's running but does not deliver the pressure required to inject.
Is this an 8 or 16v engine - throttle body or multi-point injection? If it's throttle body do NOT wire the injector directly to +12V or ground.
