Question about 1985 Ford Bronco II

1985 Ford Bronco 2 choke plate not closing

Been having fuel issues with my truck and replace the mechanical fuel pump on the block. Fired it up and ran smooth, went down the road like a mile, and it died, started looking around my carb and noticed the choke plate was sitting straight up. after looking around for a while I got stumped, this is my first vehicle I've had to work on with a carb, so I don't know a whole lot about it. I assume I need a spring to keep the plate closed but i'm not sure, any help would be great

The choke butterfly (choke plate as you call it) can only be partially closed when the engine is cold. It is used to create a low pressure under in the throat of the carby which causes excess fuel into the engine when cranking and early running to help warm up and to prevent the carby icing up. After a few minutes the butterfly will be fully open and remain that way while the engine is at operating temp. As to the engine stopping down the road look for another fault -- Like incorrect fuel cap on tank , blocked fuel filter, dirty air filter If the engine starts easily and runs I doubt that the fault will be in the carby.

SOURCE: ok someone please help me

fuel pump is a likely cause as it will run fine when cold and once it heats up it loses powers muffles backfires and dies.

Does your "wait to start light come on"? If not check fuse#22 under the hood. If it is blown it is most likely your fuel heater inside fuel canister. Unplug the wire on drivers side of fuel canister, replace the 30 amp fuse and try to start. I hope that helps!

SOURCE: I replaced the fuel pump and the car ran fine.

I would make sure that the fuel pump is getting power. If so I would return the pump. Sounds like it's a bad one.

I need to chage the fuel pump on my 85 bronco 2.8L it is on the block and I can not access it!!

If it''s on the block, it's an older mechanical type, which is in the front
of the engine, towards the bottom of the timing cover. You may need to
jack the vehicle up,to get a better look at it. There is only a few bolts
and one or 2 fuel lines attatched to it. Not a hard repair.

How to install a new fuel pump on a 1985 Chevy,305 V8,

Remove the plunger rod by removing the plate that is bolted to the block. Clean all parts if needed.

Apply some axle grease to the plunger rod and reinstall into the block, replace plate, then carefully install fuel pump, making sure the plunger is under the push rod.

Just did this same thing on my '66 283.

Fuel Pumps!

Most Ranger/Bronco II vehicles had a dual pump system up until 1991 when the Bronco II was replaced by the Explorer. While you more than likely do have two fuel pumps, the best way to be certain is to look. if you crawl under the truck, right around the driver's door, and look on the inboard side of the frame, there should be to bolts coming through the bottom holding a plate onto the frame. if that is there then you do have two fuel pumps. That is a blocking plate to protect the HP pump from road damage. It will not be there if there is no pump, and it IS important to have if you have the 2 pump system.
