I'm afraid you have an entirely different system there and they are not interchangeable. The 99 uses a single feed, variable pressure fuel system and the old one uses a recirculating system. You may be able to resolve it by using the complete intake manifold off the old engine.

No, I'm afraid not. That's a whole computer controlled system. You made an incompatible swap.

No, the car doesn't have an operating system for that. There are sensors and wiring for that fuel supply system integrated throughout the operating system.
