They have an internal diaphragm that can rupture when it gets old.
You haven't specified whether it is in-tank or mechanical. A mechanical fuel pump will very often fail after the engine overheat. Likewise, an electrical fuel pump will fail from contaminants or other causes of overheat to the pump itself. So, in short, yes!
If you mean replacing the electric pump with a mechanical one, that is not possible.

NO, it has only one fuel pump, and it is mechanical.
If you are running the fuel injection....absolutely not. No mechanical pump will provide the fuel pressure needed to run it. I don't even know if the 93 still has the mechanical fuel pump mount. Even if it did, the camshaft wouldn't have the fuel pump eccentric to run the pump.
Yes it does. But you can not run a mechanical pump on a fuel injected engine. It will not pump enough fuel to run the engine.
Mechanical
No, there is no way to operate a mechanical pump on your engine.
It doesn't have an electric fuel pump. It has a carburetor and a mechanical fuel pump. So there isn't a fuel pump fuse.
You fail to list the year, so it is impossible for me to answer. If your car is Fuel Injected, it has an electric fuel pump. If it has a carburetor it has a mechanical pump.
If the pump is new, the most likely cause is a clogged fuel filter or line. Broken line, cut hose, improper instilation.
Is it an electronic or mechanical
