hello i need help with a fuel pump issue on a 1994 coachmen santara with 460. I never had any issues with this rig untill i parked it after camping and went to start it a few months later and will not fire. I can get it running with carb spray so i narrowed it to a fuel delivery issue. i disconnected fuel line before fuel filter and no fuel when cranking. I checked that inertia switch and no problem found there, cant find the fuel pump relay because i dont have a manual. i do not here the pump running when i crank it over so now i have checked power and ground at the connector to the fuel pump. i dont have a wiring diagram so maybe someone could help me here. The connector is a four pin connector, i have a test light and its showing a good ground from a black wire and a orange wire on the pump side connector. I also have power comming from a yellow wire but my test light illuminates weak. I have another power wire which looks pink or red and illuminates brightly when key is on then it turns off and back on when cranking engine over. Now to me this sounds like a bad pump and looking for someones opinion or maybe has a picture of the fuel system wiring. thank you
