1984 F-350: crew cab My fuel gage switch in the dash

Posted on Feb 5, 2014

A 1984 F-350 crew cab w/a 460. My fuel gage does not work and it will not pump from the front tank, were do I start I have replaced the switch in the dash and the switch on the frame. I just turned it on and did not hear anything. The pigtail that goes into the frame pump has power to all the pins with the switch in the cab on the front tank. With it on the rear tank the end pin(by the blank hole) is not on.

I will gladly increase the payment if you can get this fixed for me. I will check this and get back to you when I get home from work this evening. Sorry it took so long, I check both wires and they both have power with and without the ignition on. You did something wrong. You have just verified all the inputs to the relay and replaced the relay itself and it still doesn`t work. Something is wrong with your tests. Then I will go back and recheck everything that I have done. To make sure that I checked the right wires these are the ones I check: The red wire to the tank pump, coming into at the top of the tank. The ones you mentioned to the relay, and the ground. Correct With the key on and the switch on front tank, you should have power on the brown with white and the pink with black and ground on the Black wire. With all this, the relay should energize and power the red wire going to the front tank I am going to interject because I looked at the diagram and there are TWO Brn/W wires going to the relay. One is the switched power from the dash selector (the one you`re looking for power at), the other is the relay output to the REAR tank (the one you already know is working). You may be checking for power at the wrong one.
