1994 Mustang Fuel Pump Issues
I have a 1994 mustang that the fuel pump isn't working correctly or I think it isn't.
I have noticed lately that it will prime when I turn the key on then shut off which seems to be fine but when setting at a traffic light I have noticed it cycles and when it does it changes the rpm.
I thought the fuel pump was to run all of the time, am I wrong? If it is supposed to run all the time what may be going on? What controls the fuel pump?
Thanks,
Kevin

I just changed my fuel pump in my car. While it was in the air, I changed my O2 sensors also. I don't know whether or not the pump supposed to constantly run. I noticed that when I turn my key to on, I hear the pump start up. So I don't think it constantly runs
