Since most modern automotive engines are EFI, I'll assume you're asking about one of them.
EFI engines require that fuel be delivered to the injectors at a specific pressure. That pressure is determined by the engineers who designed the engine and EFI controls.
Low or no pressure to the injectors can certainly act like the vehicle is out of fuel, but it may just be a delivery problem.
The computer turns the fuel pump on when you try to start the engine. If the engine doesn't start or if the computer does not receive a signal that the engine started (even thought the engine may have started briefly), the computer will turn off the fuel pump within a few seconds.
There are several reasons why an injected engine may not be receiving fuel:
* The computer does not turn on the fuel pump (possibly a sensor or the computer... probably NOT the computer though, but it's possible) * The fuel pump is working but fuel is not getting through (possibly plugged fuel filter or fouled injectors) * The computer is trying to turn on the fuel pump but the fuel pump doesn't pump anything (possibly a failed fuel pump, failed relay, blown fuse which usually is the result of a failed fuel pump or faulty wiring or just plain out of fuel) This is where it becomes valuable to possess some basic diagnostic skills.

Does the ignition switch have anything to do with the fuel pump?
It might have. If it's an electric fuel pump odds are it won't run unless the ignition is on.
1994 ford escort that wont turn over but has a strong battery and starter now i am wondering about the fuel system like the fuel pump or ignition module what do you think?
Same thing happened to my 94. Turn your ignition to the on position and take a screwdriver and bridge the two terminals together on the starter. If it turns over it needs a new ignition switch. Good luck on that. They are a pain to replace.
