Hey guys im new here. I recently bought a 1997 f250 HD 460 5speed 4x4. This is my first 460, I put gas in my front tank today and the pump kept kicking, (I had 2 other fords that had clogged necks) I assumed clogged neck, Well started messing abound and noticed I heard sloshing around. My front tank is completely full (reason for pump kicking) Well I switched to front tank and noticed when I turned my ignition on and my fuel pump on the front tank wasn't turning on. Im trying to find the location of the fuse on the truck before going and buying a new pump. (Dont have a manual and have had a terrible time looking online for the information),

 

If your rear tanks pump runs when selected then the fuse is OK.
Sounds like you have a bad front pump.

 

I forgot to mention I was also wondering if they where on the same fuse. Thanks That what I was looking for!

 

But you could have a bad selector switch on the dash or bad wiring or plugs to the front tank from the selector switch.

 

Its usually the srlector on the rail or the dash selector. I have my rear tank removed and a switch put in the dash just to turn the pump on and off because those original switches are garbage. You can jump through the existing pump relay if both pumps quit to bypass it altogether. But if one pump works, try flipping the dash switch back and forth really fast a couple dozen times and see if the front kicks in. If not, check the pump and then the swith. Do whichever is cheaper if you can't figure out which is being faulty.

 

Well, I think the switch is fine becasue the back tank shuts off when it is switched the the front. Do you still think it could be the switch?

 

On my truck, when I had both tanks in, I could have the front tank working (front tank has always worked) and switch to the back tank and I'd get nothing. So I had a pump that was known to be good laying around that I put in, still nothing. So I asked my uncle, who has been working on ford trucks since before I was born, and he said to run the switch up and down a bunch of times because the connection inside could be a little corroded. So I did that and I could get the pump to whine, but it would cut in and out and wasn't reliable. So I hotwired the pump by jumping wires in the switch and got it to run consistently. So the switch itself was junk, and the pump was fine. I replaced the switch with one from a parts truck I had, and about 6 months later the back tank quit working again. Turned out to be the switch again, and I wasn't going to keep putting new switches in, so I just took out the back tank (which was starting to flow gas from one tank to the other anyway) and am running a toggle switch to run the front pump now. I would try the switch, because that will be a quick indicator of whats bad. if you run direct power to the pump and the pump doesn't engage, the pump is junk.

 

Ill try that in class today (going to school be be a mechanic) I owned a chevy before this ford and every other day something was going wrong with it. SO i know every nut and bolt on that thing from digging into it so much. BUt havent really had to dig into my fords yet. Im sure I will one day but not yet. Also have a chevy for sale if any one is interested haha!

 

You do not have the selector on the rail he was talking about as that was only on the 1989 an older Ford trucks.

Because one side of the switch is good does not mean the other side is good as in the photo below. You also have a different stile and position for the switch then he was talking about.
