Fuel Relay 85 F350 4x4 std dump body

Check under the hood, passenger side inner fender, should be 2 little relays there. One or both of them are for the fuel pump, also there's a little round plastic thing in there somewhere with a sponge inside it and a round cap on it, don't know what it is, and it doesn't look like it does much, but I remeber mine going bad at some point in time. And my truck would start but not run as well.

Thanks for the response, but another snow day, another day with no plow truck. No relays on passenger side area of fender under hood, other than the starter relay and the charge controller. The inertia switch is in passenger compartment against the passenger side firewall just above where feet would be if a passenger wanted to ride in this truck, which is highly unlikely. Any other ideas as to where the fuel relay might be?

Do you have a fuse box over the passenger side fender next to the starter relay? If so, then I would guess that the relays are just below that fuse box. Everything else you describe matches my '90 BroncoII exactly. (I haven't looked at that part of my '93 F-150 and it isn't nearby) On my BII, the fuse box can slide up and out of the retaining bracket allowing access to the relay box below it.

Nothing on either fender really - Passenger is only start relay and alternator regulator. On Drivers Fender is only the computer module and the add on hydraulic lift controls for plow. I did short out the initertia switch this afternoon to see if that was it and it will still not run in the run position ( will start - pumps gas during the 'start' operation, then stops when in 'run' ). Asked Ford dealer about it yesterday ( one of my customers ) and they thought that I would find two relays on the drivers fender and a white ignition terminal box on steering column... nope, none, nada. Can't get to fuel pump really cus its under dump bed which is hydraulic and requires a running engine to raise. Well I'll try to hot wire it some how. ( also looked around under dash)

Thanks for interest everybody.

I finally found (and replaced) the Fuel relay. It was against the dashboard wrapped in a wiring harness on the drivers side of the engine compartment. Now to get the Carb to stop overflowing fuel. It's either one thing or another - now to much gas. Thanks Seasons greetings.
