Ethobling Posted September 26, 2019 Share Posted September 26, 2019 Hello. I am a guy from SE NC who recently (2 months ago, I think) bought a 1983 F-100 with the wonderful straight 6. I named him "Baruch," which means "blessing" in Hebrew. So far I have rebuilt the drum brakes in the back and have the calipers to redo the front brakes (I suspect they are sticking seeing as how the pads and rotors have much life left in them) and plan on trying to diagnose why Baruch wants to cut out after I try to start him (I have to pump the gas multiple times and then have to rev it for a few seconds before he will idle on his own). I suspect it is a fuel pump/filter, but I am new to fixing cars/trucks. He has significant rust in the bed, so I already took some time yesterday to go to the local "pick and pull" and look at some truck beds from 1980-1986 F-1xx(s) in the junk yard. Most of them look in excellent condition. I do have a question, though: can an 8 ft bed go on Baruch if Baruch only has a 7 ft bed installed now? The oil pan is leaking, so I ordered a rubber-coated gasket (since I didn't like the idea of a cork one) and it comes in tomorrow. He needed an oil change anyway :) Any tips/tricks are appreciated. I am young and new to fixing cars and truck in general, but want to be self-sufficient and now have to pay what little money I have on mechanics' "labor costs." Thank you.

Gary Lewis Posted September 26, 2019 Share Posted September 26, 2019 Welcome! Glad you found us. I'm sure we can help. SE NC? We have a member's map (Bullnose Forum/Member's Map in the menu) and I'd be happy to add you if I knew what town you are in. On the bed, no you can't easily put a different length bed on. So if you have the short bed you need to look for another short bed. (I'm sure it is possible to put a longer bed on a short frame, but it wouldn't be right nor easy.) On having to pump a lot to get it to run, that sounds like the choke isn't coming on enough. The instructions for setting the choke are included here: Documentation/Fuel Systems/Carburetors, Chokes, & EFI/Carter YF & YFA 1BBL Carbs.

Wilmington NC Yeah, Baruch does idle really low, almost wants to cut out. My brother thought this might have been the issue. Thank you for the resource. If I get time today (after dealing with the front brakes) I will definitely adjust the idle. Will keep you posted. Link to comment Share on other sites More sharing options...

Thank you for the resource. If I get time today (after dealing with the front brakes) I will definitely adjust the idle. Will keep you posted. You are now on the map. But, you may not have understood what I was saying. There's a choke on the carb that is used to enrichen the air/fuel mix when the engine is cold. And what you described sounds like a lack of choke, a problem that shows up only when the engine is cold. So while the idle speed may be low and need to be corrected, it probably isn't the problem that is causing the engine to be hard to start when cold.

So if it isn't the choke, is it the fuel filter/pump? I suspect it could be one/both because I turned the key into the run position and couldn't hear a pump turn on. Thank you for the choke resource, 1986. Link to comment Share on other sites More sharing options...

The choke and the idle speed are two different things. I mentioned the choke and it seemed like your response was that you'd adjust the idle speed. But maybe I misunderstood. Anyway, you may need to adjust both of them. And that resource tells you how. That's from Ford's factory shop manual, so is what the dealer's techs worked from. While it is probably quite accurate it may assume a level of knowledge that not everyone has. Link to comment Share on other sites More sharing options...

There should not be an electric fuel pump on a 1983 six cylinder engine. It came equipped with a mechanical pump, so one will not hear a pump when the ignition is turned on.

I'm extremely new to carbs (my Taurus has fuel injectors, obviously) and will be doing some research to get myself acquainted with them. I suppose I will need to adjust the carb a bit. If that doesn't keep the idle correct, could it then be the filter and/or pump? I assume, though, that the mechanical pumps are more reliable than electronic ones?
