Fuel Pump Relay Problems

Having problems with my fuel pump. I believe it's the relay because the pump works sometimes and doesn't others. When I disconnected the relay and reconnected it the pump works correctly. I'm puzzled!!!! Can anyone help?

Thanks, Matt

Fuel Pump Relay Problems

Had a problem with my fuel pump on my 89 Bronco II. Work some time than not. Sometime it would buzz & sometime the pump would not cut off. Turned out to be a broken wire in side of the EEC relay that controls the EEC & fuel pump relay. Tap it & it would work . I used & Ohm meter to figure out the relay had a broken/loose wire on the inside. I would pull each relay & check them out
