When you disengage your engine's power, the intake has a level of ambient pressure that needs to be released at a rate that does not damage your injectors and maintain current level of air/fuel mix in the entire throttle body. You also are hearing the exaust being released which must stay at a certain intake/exhaust ratio managed by your car's CPU. So your engine blocks the fuel flow to the injectors but continues to allow some air to enter the firing chamber to crest a negative intake pressure and a positive exhaust pressure. This locks up your engine naturally. Commonly known as engine exhaust breaking. Now your fuel pump may be surging to keep the fuel lines full for a quick restart.

Fuel pump noise fiero?
If it is loud (louder than other GM cars of the same era with fuel injection) I'd suggest you get it replace BEFORE you are stranded. Running out of fuel damages the fuel pump. They all do make some noise, but the noise is not "loud" Sometimes the baffels in the tank break and pieces of the baffels lodge in the fuel pump.
