hey I'm having a problem with my fuel system on my 1991 ford f-150 (it has a 300 in-line if that helps any)...but anyway the pump wont make noise like its supposed to when you turn the key on all it does is the relay switch makes the clicking noise. I have check the inertia switch by crossing the wires and the fuel pumps still wont work then(dual tanks)...then tried switching to the front tank it doesn't help either...the system has power to the relay
