Have Ford Questions? Ask a Mechanic for Answers ASAP
Hello, my name is***** you tell me if you are testing the fuel pump after it fails? Is so what are the readings? Does it have an internal open circuit?
Does the relay itself melt or what happens to the relay. I am just trying to get an idea of how the relay is failing.
There are only two things that usually make the relay go bad. Either the fuel pump itself is bad and is drawing too much amperage, or the relay is not being turned off so it may be a module or ignition switch problem.
