1991 Dodge Dynasty fuel shut down

I have a 91 Dodge Dynasty that seems to be starving for fuel. When you energize the pump a couple of times the car will start and run for about 10 seconds and then will stop running. I have changed the fuel pump, ASD relay crank sensor, cam sensor, fuel preassure regulator, fuel filter and map sensor any other suggestions on how to get my car back on the road would be absolutly amazing
