Dare I say... 'bronco'

[speed_deed]

First off, Broncos are built weird in omparison to our K-series.

My friend came back from Iraq last week on leave and happened to pick up a couple of broncos. I let him park one in my back driveway where everyones fords seem to collect and promised him we'd have it going by the time he goes back. I put in a starter and freeze plugs, which is 'all' it needed to run. B.S. I finally got it runnin when I pour gas in the carb but dont know where to start elsewhere. It's my day off and I dont want to be tied under this stupid son of gun all day, suggestions?

what year? what engine? what carb? what options?

if you got it running by pouring gas down the carb, id say its a fuel pump, or the bowls are draining, and MAYBE a clogged fuel filter. If the truck has been sitting for a long time, the filter is a cheap thing to swap out and see if it solves the problem. someone more versed in carbs would have to chime in, but i dont think carbs need to be primed.

if youve got compression, and spark, which you obviously do, its simply a problem with fuel delivery.

Aren't the Furds those silly motors with the fuel pump driven off a bolt on eccentric in the front timing cover , and the distributor up front where the fan can spray water all over it ?

Yeah they are pretty weird compared to a K5 !!

yup... thats the ford i know too...

Talk to thatK30guy, he seems to know a bit about vintage Fords...but then year, engine, etc would help a lot.

I had two "Early Bronco's" a 68 and a 70, both with V-8's and 2bbl carbs. What year Bronco you got and what motor??????????????????????????????

 

[speed_deed]

It's a 79 with a 351 Windsor with a 2bbl, automatic.

It is just like a chevy when it comes to fuel & spark. If you gt it to run off of a gas can, you need to figure out why the carb is not getting fuel.

Is there gas in the tank?
Is the filter clogged?
is the pump pumping?
Is fuel getting to the carb?
After all that it is prolly the carb.

In seven years of wheeling the Fords with front mount distributors, I've never had any problems with the distributor being located in the front of the engine. While on this topic, I'll point out a few more "benefits" of GM's superior engineering vs. Ford products of similar vintage.

The Ford starter solenoid is mounted on the fender well, where it stays cool and is easy to work on if need be. I wish it were right on the starter where the Chevy ones are at, oparticularly if the vehicle has headers. I miss the sound of a heat soaked GM starter trying in vain to start a hot engine.

The frame around the steering box area on the older Ford's are pretty boring. They don't offer as much of an opportunity to crack & break on the trail. Frame repairs on the trail rock!

I'd like to convert my fixed yoke T-case to the cool slip yoke design....in case I ever want to shower the earth with tranny fluid in the event of a rear drive shaft failure.

Most of the Chevy 205 T-Cases (if they have it) have the weight saving lighter duty shafts. Ford used the heavy beefy units instead....yuck.

That C6 transmission in the Ford's of 70's is pretty weak too.

The power steering system (at least mine with an OEM Saginaw pump) sucks. It is quiet and turns 42" tires. On any given wheeling trip, one of my favorite sounds of the season is my buddy's K5 Blazer's power steering belt slipping & screeching nomatter how many times he tightens it. The sound of it it synonomous with a trail ride....it's akin to baseball, hot dogs, and the crack of the slugger's bat hitting the ball.


Please keep in mind that this is all said in a laughing manner.....I was only going to post one or two points, but several came to me in a hurry.

You probably coulda saved a little time and posted what you thought the problem might be too



back to the topic at hand. I'd say it probably would be in the fuel system also as stated already.

Id love to have a 79 Bronco Wayyy stronger than a K5. Better Arival/departure angles.
Bullit proof ford 9" rear axle. 351 Ws rock. Lots of power to be had with little $$$. Other good strong stuff as stated above. Why Ford scrwewd up a great off road truck and went to TTB front and D44 rear ..??? Prolly the same reason GM went IFS .
As for not starting.... It has been covered pretty good. Fuel pump, Fuel filter, dirty carb. bad gas.

Back to the original topic here, it's a pretty simple problem...if it runs while dumping gasoline down the carburetor, the ignition system isn't the problem....the problem is in the fuel system.

I keep a cheap $40 electric fuel pump in the garage for problems like this. If you have one, hook it up to your existing fuel system (under the hood), run jumper wires to the battery, and see if it will run off of the electric pump.

I'm not suggesting that you leave the electric pump on the vehicle, under the hood (they are designed to push fuel, not pull it), but it will work for testing purposes. You could replace the fuel pump, filter, and fuel line on that vehicle for roughly $50 total.

The theoretical 1979 Blazer vs. Bronco summary:
Front axle: Basically equal in strength.
Engine: Chevy has the advantage (350 sbc vs. a 351M/400). A 351 Windsor was not used in 1979).
Transmission: Ford C6 is stronger than a TH350. Pretty sure TH400's weren't commonly available.
Transfer case: Ford 205 is stronger.
Rear axle: Ford 9" would be preferred.

With all of that said, the transfer case and transmission differences isn't that big of deal....they aren't common failure points on the trail.

Also, in 1980 when the Ford body style changed, the Bronco/F150 continued to use 9" rear axles for a few more years. They were common until 1983 or so, when most F150's Bronco's went to the 31 spline 8.8 rear axle. D44 rear axles (if used at all), weren't very common. Ford still used some leftover 9" rear axles after 1983-1984....I had one in a 1985 F150 several years ago. Yeah, it could have been swapped in, but Ford was notorious for "raiding the leftover parts bin."

GM wasn't much different in that regard.

The '79 grill is my favorite looking older ford.
