Should be but that doesn't mean your injectors are firing. Check them by either using multimeter or remove injector and start to see if fuel is coming out.
Preasure your fuel tank. Take a cloth and put over your gas tank fill and use a air compressor to blow air into the tank to build presure. This should build up presure and react the fuel pump to pick up the fuel.

Look for a bad fuse or relay. If both check out, most likely an ECM problem

If the oil pressure switch has two wires on it it may be one that shuts down the pump. I'm not positive but I think it completes a ground circuit, not the hot side though (but may run through a relay.) There should be a pump relay under the hood with a group of other relays. I don't have a wiring diagram for your car but you can get a basic diagram in most inexpensive manuals. They wont usually give you locations but at least you can get an idea of how the system works. There usually is a fuse. If the fuse block is not labeled, use a test light and probe the back of every fuse for power with the key on (takes about ten minutes and faster than trying to find info) change any that are blown. The most likely culprit is a relay, so after testing fuses look for it. (usually on drivers fender or on right side near firewall.) Worst case, trace the power lead all the way through the harness 'till you find where power begins.Testing is important here...I could give you much better info if I was there to do it for you. Most important is to stay "on track" till you find the place where power ends. Don't jump all over the place or you will end up doing an incomplete test.

Check for 12 volts power at the fuel pump harness. If no power is going to the pump, check the fuel pump relay. Also, check the fuel pump inertia switch. Ford usually has it on either inside left or right rear trunk fenders.

How about just rolling up carpet behind seat and accessing fuel pump cover. unscrew cover sc.rews, disconnect plug and hose clamps use 8mm socket to pull bolts. Much easier than pulling gas tank
