bought a 1977 bronco from my uncle last spring. finally decided enough was enough and im sick of it being parked. it hasn't ran since 1993. my uncle claimed it does run but has an electrical issue of some kind. the story is he was backing a boat into the river and the alternator wires got cut by the fan. he spliced them back together and it woudnt start so he parked it in his garage and there it sat until I bought it. hes not really all there.... so im not sure what the real issues are. needed cash to fund this project so on Saturday I sold my 1966 ford mustang. might regret it someday but im more of 4X4 kind of guy anyways. changing all the fluids, spark plugs, wires, cap, rotor, some fuel line, fuel filter, new battery, new ignition switch and ignition module. he took the ignition stuff out for another rig so gotta have them. do that tonight and we'll see if the motor turns over. motor has 40,000 on it. my uncle bought it in august of 1977, the guy that had it before him owned the dealership he got it from. might get lucky and get it to run, if the motor is garbage then I have then cash to rebuild it or replace it. good ol 302 backed by a c4.

Here's some pics

I love that rig. I had a nice one, same year....and like a doorknob I traded it away. At the time I thought I was doing a good thing aquiring a 72 F100 but I sure wish I still had that Bronco.

:drool:
-
awesome, I restored a '71, wish I still had it.
-
She will crank and start!!!!!!! :tup:
-
I have a 76 that my uncle bought new. you would be supprised what that old bronco is worth they are getting harder and harder to find that are not beat up or rusted out. That's a cool ride. :tup:
-
:drool: I'm envious. I dream of getting a '77 someday.
-
I read ford is reincarnating it and with a diesel option.

You've got to be kidding? If that's true, I want one! :drool:

Love the 66-77 broncos. If I ever get tired of the Jeep an early Bronco will be built.

If that link is what the new Bronco will look like, I'd prefer the '77.

Don't forget to clean the carb as it will have gunk :bash: in the bowls or jets.just pay attention to the turns out clean it with air,or better yet soak the carb,lemon juice , new gaskets. should go. :IBCOOL:

Why would anyone go for that when for a mere 150K-200K you could have an Icon (http://www.icon4x4.com/overview/br/models)... :chuckle:

congrats on your new rig, I have a 1973 sport that i'm currently working on and hope to have on the road this coming summer
-
nice!!!
-
Great project!
I love those.
-
Check all the wiring. When the fan cut the wires it probably shorted out the fuses and possibly Fusible Links (if it has them) or other components? Those old Broncos were neat, and getting harder to find. Soon so will my beloved Ranger pickups and Bronco II rigs. :tup:
-
well for an update! the tanks were clean. he syfonned them out. yeah I know that's spelled wrong.... but anyways. changed the fluid and parts hooked a battery up and this thing turns over and started right up with a little gas in the carb! put 5 gallons in one tank and its not getting to the engine. should have checked the fuel lines before anyways so that's where ill start tomorrow after work. very impressed that it wants to run though and sounds smooth turning over and when firing. I think I might have gotten lucky on this one!
-
May just be a clogged fuel filter. The book said the fuel filter on my '86 Ranger was good for life. I don't think they expected the vehicle to last 35 years! Anyway, it turned out to be the module on the distributor. The Mechanic said he'd never heard of one quitting, then running good for 2 more months! :dunno:
-
It's got a brand new wix fuel filter. The clear kind and fuel isn't getting to it. That's crazy about your ranger though!
-
I'd like one day to get my hands on that full sized 78-79 and build it up...
-
I've always liked those and have thought about picking one up and rebuilding it, way to go.
Be prepared for gasket failure once you run it for a while, after sitting that long without running its likely going to need new ones, but that will be another nice winter project. :tup:
-

It's probably the fuel pump, then. If it's an engine-mounted fuel pump, the diaphragm in the pump is probably cracked and not pumping. Easy to replace. If it's an electric fuel pump in the tank, I feel for you. (I can remove the fuel tank from my '90 Bronco II with my eyes closed!) :chuckle: My '86 Ranger has 2 fuel pumps= a low-pressure electric pump in the tank, and a high-pressure pump on the frame rail. That was the first year for the fuel-injected 2.9 V6, and that was their answer to feeding the fuel injection. Fortunately, the previous owner ran the truck twice a year, so they both work! :tup:
-
Yeah it's an engine mounted fuel pump. So just replace the whole thing then if that's the issue?
-
Yes, very well could have a split diaphragm.
-
I will try to post up a picture of my brothers bronco...
-
I know its dumb, but a 66-77 Bronco is #1 on my wanted vehicle list.
-

That's probably the best thing to do. That way everything in it gets replaced. Back in my day we just bought a new diaphragm and changed it. Don't know if you can buy just a diaphragm any more. Get an LMC truck catalog. I got the Ranger/Bronco II one. Even if you never buy anything from them, it's a wealth of knowledge as to what is available for these old beasts! It even has a page on the model year history and the changes made to each series as the years went by...
-
Another thing I gotta figure out is electrical. Hook the battery up and there is a red brake light on the dash that lights up with the ignition off. Turn the key on and it goes off. No clue
-
Sounds like a faulty emergency brake light switch. It's too old to have an ABS system. The Chiltons Manual I have for the Ranger/Bronco II series has electrical diagrams for all the years. A guy at NAPA printed me out a diagram of a system that wasn't in the book. Keep it up, and you'll be an expert on those things! :chuckle:
-
That light goes to your proportioning valve, if it come's on and then goes off its doing what is suppose to.
-
Proportioning valve? It's suppose to be on when the key is off and not even in the ignition? Like I said I'll turn the key on and the light goes off.
-
That might be it.. The Brake system is hot all the time, and the ignition switch might bypass it. Run it for a while--Sometimes when a vehicle is idle for a while, the electrical contacts gum up, and work good once they are used again... If after a month or so, if they still act up, then start trouble-shooting. :twocents:
-

It will be easy to tell after a month because your rig won't start anymore and need a new battery. :chuckle:

Depends on the battery--the instructions that came with my CB radio advised hooking it up to a switched circuit, so it wouldn't get left on and drain your battery. I inadvertently left it on for a week, and my Bronco II started right up! :chuckle: Sounds like he is only connecting the battery to run it, though. Some vehicles develop a "Dark Load", and the battery runs down overnight, and those can be hard to locate! :bash:
-
Brings back memories. First vehicle I ever owned was a 69 Bronco. Traded it off for a brand new 76 Bronco. Often wish I would have kept it but not sure where I would have stashed it.
I rescued so many people stuck in the snow while running my trapline. It seemed like it would go anywhere. I even towed out a family riding snowmobiles that were stuck and couldn't make it back out to the plowed road.
-
Put a new fuel pump on it. Blew through the lines and they're clear. But not hearing bubbles in the gas tank. With half a tank we should hear bubbles when blowing through the lines. So tomorrow we'll drop the tanks which we really should have done before anyways and see if the pickup tube in the tanks is rotted off.. At least the fuel lines aren't plugged..
-
I am far from a ford guy but man I love those old broncos. :drool:
-
Are you sure you have the fuel tank selector in the right position? Its on the right side under the drivers side seat. Check all your fuel lines there probably cracked and sucking air.

In this case, with it turning on when the ignition is turned off its almost certainly being swithced with a relay. Most relays will draw a few amps of current, which would drain a battery in short order if not disconnected when not in use, which will become a PITA eventually. Best to just track down the problem. :twocents:

Yup. A vehicle that old, and sitting unused for a while, they might be. I changed all the belts and hoses on my '86 Ranger, too. They looked good, but that old, you never know. They were all mostly the originals. I had to take just about everything off the front of the engine to replace the valve cover gaskets anyway. I learned with my '91 Ranger that leaking valve cover gaskets eventually kills the starter.
-
Yeah so we'll drop at least one tank tonight and see what's going on. Battery is unhooked unless we're trying to start it. I'll worry about the brake light after this thing is running. Once I get running good I'll start fixing up the interior and exterior, exhaust, lift kit and new tires. Already have new wheels for it. Can anyone recommend a lift kit? Can't make up my mind on if I want to run 33s or 35s. Not going to be a wheeling rig. Mostly one I'll cruise around in and maybe take up to the mountains for hunting.
-
So does yours have a 3 on the tree or is it an automatic?
-
:tup: One word of advice for dropping fuel tanks I learned the hard way: Make sure you siphon ALL the gas out of the tank. even 3 gallons makes the tank really heavy! :chuckle:
-
Take a look the stuff James Duff has.

-

Automatic
-
Having an automatic is better. Before I got mine the guy I purchased it from bought one of the Duffy conversion kits and moved it to the floor. As most of those that had it on the tree were notorious for having problems like slop, etc. So when I got it I purchased a 4 speed out of a early 70's pickup and bought an adapter out of CA and installed that. Now when I am in 1st it crawls and in 4 wheel low/1st it really crawls.
-
Getting fuel to the carb now. Tank was spotless and the pickup tube in it is in great condition. Didn't know they put plastic gas tanks in these. Sure glad they did. Carb is gonna need a rebuild or replaced. It's got a ford 4 barrel on it. Still won't actually run but it fires. Uncle said something about the ignition switch getting hot a couple times. I'm thinking there's a messed up wire or something. I remember on my 79 bronco I had it woul do the same thing. Fire but not run. Ended up being something with the ignition but not sure what. Ended up selling it before I tried to fix it.
-
If it sat with gas in the carburetor for very long, it might have gummed up the carb. I bought a snowblower that sat for 8 to 10 years with gas in the carburetor and it was so gummed up I just replaced the whole carburetor. I never fooled with 4-barrels. 2-barrels were complicated enough for me! :chuckle:
-
Yeah I decided I'm
Just going to buy an Edelbrocks for it. Anyone know which one to go with for a 302? I was thinking the 500 or 600 cfm. Not sure which would be better for it though.
-
With the price of gas these days, I'd go with the one that gives the best gas mileage. What little I know of 4-barrel carburetors is that they normally run on 2 barrels unless you stomp on it to open the auxiliary other 2 barrels. Avoid cracking the other 2 barrels unless it's an occasional "get the cobwebs out." That's when they really start to drink the gas! Calling Edelbrock, or getting on their website will probably tell you what model is best for all-around driving... The old claim was that a 4-barrel carb was more economical to run than a 2-barrel. As long as it only ran on 2 barrels. :dunno:

I would never lift one. You'll ruin your gas mileage with them bigger tires and they are already really hard on u-joints and slip joints because the angle is so steep on the driveline. A lift will make it worse. I never felt I needed it.
Broncos are top heavy to start with anyway.
Your choice though.

:yeah: I have to agree with not lifting the vehicle and putting the big tires on it--unless you just want to look cool. Ford paid their engineers a lot of money to design a driveable vehicle that will still take you anywhere you want to go. My '90 Bronco II is bone stock, and I call it "a little mountain goat". And I didn't have to buy a ladder to get in and out of it! :tup:
-
If you intend to drive on the freeway and in traffic, you might think twice about a lift. Early Bronco's are plenty tall for their short wheelbase and already pretty squirrely. My brother had a real nice '72 I drove for a while before selling.
-
Here is a picture of my brothers 69 Bronco

I've always enjoyed driving lifted vehicles. Never had any issues with my 2000 silverado on 38s, my 86 k5 blazer on 37s or my 79 bronco on 35s. I've seen a lot of these things driving down the freeway on 33s and 35s. They don't look like they have much for issues. I'm not looking for this thing to get great mpg. I did some research and saw Edelbrock recommends the 500 and 600cfm carbs. I think I'm gonna go with the 600 since the 500 is for 302 and smaller engines.
-
I don't think the size of the carb matters as much as the heaviness of your foot! :chuckle: As for the lift kit and big tires, It's your vehicle--build it the way you want it! :chuckle: :tup:
-
Ordered the 600cfm 1406 edelbrock! Shipping out today!

Cool! You may need 600 cfm to push those big tires down the road! :chuckle: I think 600 cfm is the maximum flow. I don't think you get that running on the front 2... :tup:
-
Go ahead and lift it, the running gear is pretty stout, and don't worry about drive line angle, these have cv drive lines. Make sure you get good springs, I had one with wild horses 3.5" rock crawler coils, (it rode real nice). Don't worry about mileage, they are not aerodynamic to start with. I sold mine long ago, but they are still my favorite..

What size tires did you run with the 3.5 lift?
-
Got a new Edelbrock 600 on it yesterday and found out a wire was broken off from the ignition switch. Spliced one in and got to drive her today! Motor sounds and runs smooth! Surprised how well it runs after being parked 20 years!
-

33's fit real nice with 3.5" of lift.

Here's some pics from today

Lookin Good!
Took the studded snows off my Bronco II today...That means winter's definitely over! :tup:
-
I came across my old post and thought i should do an update. The bronco runs. I installed a 3.5 inch wild horse lift kit and it needs an alignment, the brakes redone after being parkes so long and some of the lights replaced. Some used tires were given to me to get it one step closer to being on the road. Amazing how time flys and projects get put to the side. Between being busy at work, owning a house, and a 4 and a half month old daughter thats exactly what happened. I still go out and start it up about once a month. Slowly but surely ill be driving some day!
