1st I hope you are taking the fuel pressure from the correct side of the system. The correct side will be the side coming from the fuel filter and before the fuel pressure regulator. At a normal idle, the pressure should be roughly 30-33 psi. When you crack the throttle rapidly, a sudden vacuum drop will cause the diaphragm in the fuel pressure regulator to shift causing the fuel pressure to jump sharply. Usually to 45 or 50 psi. You can check the maximum fuel pressure by dead heading the pump. This can be done by simply pinching off the return hose to the fuel tank. At an idle, the maximum fuel pressure the pump will put out will be displayed. You will also notice a slight jump in rpm's because it cause the fuel mixture to fatten up before the ECM can respond to changing the pulse width based off of the o2 sensor.
I hope my answer was satisfactory.

SOURCE: where is the fuel pump for a 1987 Maxima by Nissan
The fuel pump is located under the rear seat. You will need to remove the rear seats to gain access for replacement or inspection of the pump.

Have you had the battery tested to see if it is good. The battery should be replaced every 5 years and can be tested for free at an AutoZone or possibly another local auto parts store.
The only other thing that can run the battery down if the alternator is fine is that you have a short in the wiring. To narrow this down, you need to take an amp meter (you can buy one from an electronics store) and pull one fuse at a time (while the car is off) and see which of the fuse ports is pulling current with the car off and draining the battery.
Let me know what you find and how this works out for you.
