Look at my answer for the location of the fuel pump fuse for the '93 Acclaim. Might help you. I found the relay.
The fuel pump is inside the fuel tank on a Plymouth Acclaim.
The fuel pump relay feeds power to the fuel pump. The relay is commonly mounted under the hood with the other vehicle relays.

It is in the fuel tank.
It is in the fuel tank.
It is inside the fuel tank.
Usually between the fuel tank and the engine. Ok, it is near the fuel tank, on the passenger side. I have a 1994 Plymouth Acclaim I hope it is in the same spot as yours.

Plymouth does not use inertia switches.
Check the fuel pump relay.
Under the car, just in front of the fuel tank.
