'84 Bronco II reanimation thread

[Bryce]

So, after letting it sit over night, it cranked right up. Started and went to high idle, I let it sit on high idle for a few minutes and then tapped the gas to let it kick down to a regular idle. Moved it back closer to the garage than it was where it stalled last night. It sat there idling for a few minutes and then it stalled. cranking it up, it seemed to stumble and finally caught but then quickly died. cranked it again and it was more temperamental but started and idled for a bit.

I'm thinking the TFI module is shot, so I'll go out and get one of those. I'm pretty sure it's not a fuel or air problem right now, so it's got to be spark.
It's also painfully obvious that the brakes need to be bleed more. I damn near hit the garage when pulling up closer but luckily, it rolled to a stop just short of the back door.

I'm more encouraged today than last night.. that was a big letdown to crank it up, drive it and have it conk out in the middle of the back yard. There's still hope to get it on the road before I go back to work on Wednesday.

the fuel tank and sender and some other little parts from Rock Auto should be here for the weekend to install.

In fact in the time to write the last post, it stalled again and now there's no spark again.

TFI module and coil have been replaced and now it has idles for 20 minutes without stalling. It does stumble every so often, but it always did that and I always figured that was the crappy computer controlled carb. Revs much better now also. before it would heat up and crap out in less than 10 minutes until you let it cool off (2x last night and 2 x this morning until I replace3d these parts)

Cleaning up nicely! Doesn't look like an abandoned vehicle anymore!

I think I'm going to go get a mighty-vac to get a really good job of bleeding the brakes. They are getting better after another round of pump pump hold but I think the mighty vac will just finish it off. Then we can focus on the fun stuff!

 

[Bryce]

So, after pulling the rear brakes drums off to more easily get to the star wheel, I adjusted the back brakes out. and mighty-vac'ed the rest of the air out of the lines.. I have brakes!!!

Road test, coming up!!!

 

[Bryce]

Well, today it wouldn't start. I already swapped the TFI module and coil lAt weekend and ad the TFI modue tested (tested good multipe times). Looks like the PIP/Stator/Hall Effect stuff might be the culprit from my testing. A reman distribur shoud bevat the parts stre for me tomorrow (so they caim... I was surprised they coud get it for me on a Sunday Morning).

I have my new fuel tank and It's all ready to go. I oainted it and put the new sending unit/pik up in it. My plan was to put it in today, but troubleshooting the lack of spark wasted my day.

 

[Bryce]

Well, seems lie I'm giving up easily, but it think my Bronco II lived slow, died old and left a good looking corpse. After putting a dustributor in it today, still no spark. I unplugged the spout plug and got spark (signs of a bad computer) We got it to fire. But still woudn't run right. Wide open on the throttle, and it woud alf way run, but would not idle. In the process of screwing with it, we fried the starter. So, now, no starting and not turning over.

I'm tiring of fixing one thing only to find another problem. I 'm really thinking about giving up on the ol' girl. I think we were fixing this with our heart in the right place, but not our head. I may soon have a garage sale of parts.

Did you check the computer connector and EEC relay don`t give up just before the miracle. They are both on the passenger side bulkhead just in front of the door?

Hey your engine sounds like mine, rattles and knocks LOL. The stalling and everything could have been just stale fuel in the lines and everything as well as your TFI issue. At least the body on your B2 is in great shape, mine is horrible thanks to salt corrosion from what I could figure out. I can say this, I've had a nightmare list of problems with mine, slowly getting things worked out with it at least I can drive it around town, don't much trust it out of town yet, but I think its getting there slowly. I do plan on picking up some spare parts that I've had issues with and carry them in the vehicle in case of an issue while out of town, but other than my major rear main oil leak its running much better. Problem I'm having now is just electrical wiring that I find that's damaged that I'm trying to slowly repair.

Does anyone know if there's a way to repair the wiring connector to the TFI? I just noticed a couple of the wires are starting to pull apart close to the actual plug. Is there a way to fix this with a replacement plug of some sort? Could I get a plug from a scrap yard and cut the wires long and then solder or butt connect them together to repair, as well as do the remote TFI relocation while I'm at it.

STANDARD MOTOR PRODUCTS Part # HP4530 s the plug with short leads to wire into the harness

Is the relay under that cover with the rest of the relays and stuff? Any way. Test it? O'Reilly's has them for $18.

If I knew it was going run, i'd go ahead and duraspark it, but i don't want to shovel money only to find it's shot.

Honestly, its a good candidate for a 302. Already body lifted, C5 transmission and no AC to get in the way.

Hmm, I've tried searching all over for that part number and get nothing. Even the Standard Motor Products site. Sounds like it would be just the same to just goto the scrap yard and clip the connector out and leave some excess wires to splice in.

 

[wildbill23c]

Oops, haha, typed the wrong web address, found it for $9. Going to see what the scrap yard charges me and I may order one if they charge a fortune. Have to go over there for some stuff anyhow one of these days. That wire harness and plug fits a lot of different ford vehicles, at least I can expand my search at the parts yard if I have to for that LOL.

Rockauto.com has a better price, but shipping may negate tat unless you get other things atbthe same time.

Thanks Bryce, will be ordering some stuff tomorrow as I need a rear main seal, oil pan gaskets, and well crap can't remember the rest of my list right now but I'll order the parts after work and they'll sit on the shelf for a year like the rest of my dang projects...I need to buy extra time rather than projects I guess LOL.
