Dandy. That rules out the circuit that causes 90 percent of the fuel pump problems and proves the automatic shutdown (ASD) relay that Docfixit mentioned is working. What you are left with is the pump, its relay, and the wire in between along with the Engine Computer, (PCM) and the main feed wire to the injectors.
Listen for the hum of the fuel pump for one second after turning on the ignition switch. If you don't hear it, suspect the pump isn't starting up. The following is a copy / paste version of an earlier reply that might apply here:
At the mileage you listed, it is fairly common to have a pump motor with worn brushes that cause it to not start up. Unlike GM pumps, Chrysler pumps almost never quit while running.
Try banging on the bottom of the tank while a helper cranks the engine. Often that jar will get the pump started.
By the way, there will only be voltage to the pump when the engine is rotating, (cranking or running), not just with the ignition switch turned to "run". Depending on the model, that voltage comes from the fuel pump relay or the automatic shutdown (ASD) relay. Those are turned on by the Engine Computer when it sees engine rotation. It knows that by the pulses from the crankshaft position sensor at the rear of the right cylinder head, and the camshaft position sensor in the distributor.
